My Slim 2AA Battery Node
-
when you are gonna to use some power up/down converter, them will need more power, so your battery will be faster empty.
If you make your circuit so simple as possible, so you can reach the longest battery time.

@siod said:
I wasn't aware that the nrf24l01 is so sensitive to voltage higher than 1.9v.
Typo? I suppose you mean 3.3V.
I would like to have a sensor design to which I can add different sensors...
Please reply why you don't like those two designs I linked to in my last post above.
-
5V as a supply voltage had been the standard for many decades.
As integrated circuits have become more compact and more efficient, 3.3V and 1.8V as supply voltages have become standards as well. 3.3V for most components, 1.8V is more recent and only used in some very highly integrated circuits.
For sensornodes based on batteries, the 3.3V standard is very usefull and most sensors are available for this working voltage.
If you really need 5V for a particular sensor, then think about AC or USB powered nodes. 5V sensors are a bad choice for battery based nodes. The 5V sensors are mostly old designs, and very inefficient when looking at them from a powerconsumption point of view.
So you can want to combine 3.3V and 5V sensors, but our experience is NOT to combine and make a choice for low power (modern) 3.3V sensors when trying to build battery based sensor nodes.
-
OK guys, thanks for the explanation. In this case I need to buy new temp sensors...
The 3.7v batteries are no option for me because they are too expensive in my eyes. I didn't want to buy new temp sensors as I already bought a couple of the DHT 11 sensors but it seems like there is no other chance now.
I just think the next time I encounter problems is, when I try to setup a new sensor node with attached pir motion sensor... I will read the data sheet of it first and look out for power consumption
-
Is there any motion sensor that work on 3.3 V ? I tried powering the below one with 3.3 but it was acting crazy and keeps reporting motions.
http://store.fut-electronics.com/products/pir-motion-sensor-module-adjustable-range
It is written that V range is 3-5 but it worked well with 5v only.
-
@ahmedadelhosni Haven't you seen the motion example sensors in the first post of this thread?
-
@m26872 yeah I know you have a topic but actually was concerned with door and window sensors that time and forgot to check it again when I needed it
-
I can't program my slim node through ISP, is there a reason it isn't working.
I use USBASP with jumper 3 connected.
But it can't find the node.someone have a clue how to solve this.
it doesn't recognise the avr.
This is the error i get:
avrdude: error: programm enable: target doesn't answer. 1
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.avrdude done. Thank you.
-
When i use a ziff programming board, the avr is programmeble. so usbasp is working.
-
Finally got my v2 (red) boards in. Ended up with 30 of them. Will start wiring them up this week!

This is solved, with the use of the right boards.txt file i now can burn the bootloader from within arduino.
-
Below is my first sketch with this awsome 2aa battery powerd board.
i didn't measure the current. but i tryed to be as efficient with the power as possible.my avr is running on 8Mhz, this is becaus the DTH22 doesn't run on 1Mhz.

Finally had time to solder it. Not my best job, I admit. One of the caps I tried to mount was not flush enough so I had to clip it off. Hopefully not a critical component! I made the radio removable using some header strips. Now to figure out what temp sensor to use. I have currently used just a thermister. Can DHT22 work down at ~1.9V?
Anyway this was fun - highly recommend a needle point solder tip!
-
@wergeld congratulations
For the temp sensor I suggest a si7021 board. Almost the same price as as dht22 but more accurate, reliable and versatile. It uses the I2C bus (pin A4, A5)

Ordered a couple of the low voltage ones as I want to make my nodes with as few components as possible. I could still use my thermistor while I wait. This is a fun build!
-
Hello, I made a small modification to this project, hope that is ok! Now I need some help validating it! I opened a new topic to avoid going side topic in this one:
http://forum.mysensors.org/topic/3642/m26872-slim-node-mod
Thank you all
-
@Soloam I'm happy that you've picked up the design. That's what this openhardware is all about. Also very good that you made a new topic! So, let's continue there. I'll follow.
-
I ordered a proto pack on 15th of April and received it on 30th of April. Pretty fast, I think.
-
Hm, I built some nodes and messured the current with a Fluke 179: 15mA even with a minimal sketch with sleeping enabled. AVRs are not from china, but the NRF24 are. So, is the radio the problem?
Greetings
-
(i am using MySensors 2.0.0beta)
-
Could be radio, but who knows? What troubleshooting steps have you taken? Hw-, sw-variations etc. Please post your sketch. Perhaps are there any SlimNode users with working MyS 2.0.0 beta that can share some info.
-
@m26872
I have had a bad radio which would not go to sleep and consumed around that amount all the time (also when I used SLEEP in the 2.0 library).Switching the radio to another one fixed it. All my radio's are from China, so they are normally OK. But you can get bad ones once in a while. Given the low cost I do not care and swap them when needed.
-
Ok, where to buy NRF24's which are genuine for sure and not too expensive in europe?
-
@rollercontainer
No idea, I'm quite happy with the radio's from China (1 bad one on 25 pcs so far).
-
Thx, Gert. Are you using 1.5 or 2.0.0beta?
-
@rollercontainer
I use the 2.0 beta
-
Bought another 2 radios from different dealers. The one with the blob on the die is going down to 2mA, but isnt working at all (node does not come up). The next one is working, but again 15mA. This is frustrating. Anyone here with a good source for radio modules?
Even with a stripped down sketch without any sensors with only delay and sleep in the loop, the current stays the same.
-
@rollercontainer
I get my radio's from an Aliexpress store called AAA+ (or something with a lot of A's in the name).
-
@26872, It's my first post here and I had to register so that I could give you my regards for your work and for sharing it with us! Just ordered a batch of your v2 boards.
I have similar design sensors running on proto-pcbs, but your ready-made pcb makes everything much more convenient.
Just had a question on stability of running regular Arduino 8mhz internal clock bootloader for prolonged time. Anyone tried this and had success running the 328 down to 2v (or so) @ 8mhz? If this is a doomed idea, I will have to attach the boost circuit to this design, but it would be nice to avoid all that parasite current consumption.
-
@Bobcat
I have had an atmega328 run down to 1V6 at 8Mhz before failing completely, so working down to 2V should be OK. The nrf24 will likely stop around that point as well (lower limit is 1V9 for that chip).
-
@GertSanders
Thank you for the reply! Was the atmega doing some clock critical tasks when it went below 2v? I am thinking to attach BME280 (Pressure/Temp/Hum) which also operates in the same voltage range, but not sure if the I2C will be working properly when atmega goes overclocked.
-
@Bobcat
The nice thing about I2C is that the clock is generated by the atmega328 (the master), so even if this clock slows down due to low voltage (this happens a little when using the internal oscillator), the I2C devices on that bus just follow.
We can also use SI7021 (temperature and humidity sensor) at these low voltages for the same reason.

Hello all
I´m Henrik, first post here and sort of beginner at this ( use to do some embedded stuff some 15 years ago and picked it up again recently )
I just did a shopping list for this project, Version 2.0 if I got it correct
here it is: http://my.aliexpress.com/wishlist/shared.htm?groupId=3106453469
As an example it should be about 20 euros if you buy to be able to make 5 whole sets.I added 3 additional and optional things to the original BOM:
battery holder + battery connector to make it easier to change them ( I think )
straight pinsI did this for people searching for the components needed that does not have any or very few before starting the project.
Only thing extra needed I think would be some additional cable and a arduino UNO or some other way to program the single chips. But I assume you already have a UNO if you read this
And a soldering iron and that stuff.(if even one person found this useful I guess it fulfilled its purpose)
//Henrik
-
can someone tell me if I can find Version 2 on the new site: http://dangerousprototypes.com/store/pcbs
?I never ordered any pcb´s like this before so I don´t want to get it wrong =D.
If the models are not there to choose from unlike the old website, what file do I need to upload to have them print the board?thanks for any help
-
@m26872 has prepared for ordering this board directly on openhardware.io. Easy and you give something back to him.
-
Received mine from DirtyPCBs - I just wanted to test the whole system. I guess my first question is: how do you guys break them apart? Since tthey come in 3-circuits-per-board with little holes.
I don't want to ruin them!
-
-
Thanks, it worked!
Sorry that I couldn't find the post you linked..
-
Are there any guides on how to assemble the 2.0 version?
How should I, as I beginner, find this out?
I know about the schematics and the BOM, but, for example, I could only find R1, C1, C2 and C3 marked. The schematics shows C4 and C5, just an example - how do I find where those go?Thanks in advance,
hugo
-
@hugows C4 goes over the ground and VCC of the NRF radio. I'm not sure about but C5, from some pictures I have seen I think it goes in the same place as C4 but I may be wrong. I have left that out without an issue.
OP - this board is great! it take the pain out of soldering the radio to a pro mini / nano. I really like these.
-
@thazlett144 Thanks. like this then?
One more thing: can I mount R1, C1, C2, C3 on the bottom side? My "height requirements" aren't as strict, since my cable duct is almost 2cm tall.
--
To check, I will be soldering this 8 components in this order:
- R1
- C1
- C2
- C3
- C4 electrolitic (then bend it)
- Atmega socket
- NRF24 radio
- 6 pin angled connector
-
C4 in your picture looks correct to me. You could put C4 up on the edge under where the radio would be as well. You have VCC up on the edge. I think the pins adjacent to that are ground too. EDIT: I think I replied before you edited your picture
You can solder the components underneath if you need to yes. I don't see why that would be an issue.
-
I'll add the C4 and C5 ref-silk to the list of requests for improvements.
-
@m26872 C5 would be in paralllel to C4, right?
Also, those are the capacitors for improving the radio transmission, correct?Thanks for this awesome board, @m26872!
-
@hugows Yes, C4 is the standard recommended cap on the radio module supply and should be between Vcc and Gnd as near the radio as possible. The chinese clones are known to be very supply noise sensitive. C5 is of low ESR type and there to further increase the filtering. In theory it should be even closer than C4.
A battery supply is stable by nature and you should probably stay fine without some of the caps in other cases as well. The design is intended to provide flexibility and margin in general. It's easy to throw in a few extra parts and then maybe avoid some troubleshooting.
-
I've set up two sensors with 2 reed switches and 1 HTU21D attached. When I was testing them around 60 cm away from my gateway they worked very fine. Now I moved them to their final destination which is around 8-10 meters away from the gateway and now they don't reach the gateway anymore. Any idea what could cause this? Any way to increase the range?
-
@siod
Is there any obstruction between the nodes and the gateway? Trees, walls, etc? Depending on what is in between the radios you can dramatically lose signal.
-
each one goes around a corner and so one wall is partly between the nodes and the gateway and it´s not even concrete. I have one node in my basement attached to an arduino nano and I have no range problems...
The batteries are all fully loaded.
edit:
I would like to post my Node sketch as well as my gateway sketch and MyConfig.h. Maybe there is some optimization potential:Node sktech:

edit: I restarted my gateway and the nodes, it is working for a while, but after 1 or 2 days 1 or more nodes freeze. Does anybody else have equal problems?

I have ordered the 2.0 boards, they are on their way to my home
I'm plannign to use them as :
- temperature node
- door sensor
For the door sensor, can you tell me if I'm good :
I have to use a 1MOhm resistor between the pin of atmega and one wire of the reed switch ? So I will have the longest battery life (my atmegas are burned at 1 Mhz or 8 Mhz)Am I right ?

@carmelo42
Thanks for your support by ordering. I actually recieved another 50+ share credit transfer from DirtyPCBs today. It'll be donated to MySensors right away.If you look at post 116 you'll see the I used a 10Mohm pull-up between Vcc and atmega input pin. Reed switch connects between Gnd and input pin.

Thanks to you for providing us theses files
Ok, my mistake (I juste received my 10 MOhm resistor
Perfect, I just have to wait now for the little yellow packet

I have received yesterday my little packet from DirtyPCB
11 PCBs, so 33 sensorsI'm just wondering where the C5 capactior will go on the board .. Can't figure out

@carmelo42: maybe this helps, all Cs and the R assembled!

ups... C5 is also not there on my board,it shoud be parallel to C4!

https://img1.picload.org/image/ldrrddg/deekrobot-isp.pngCan you tell me how I connect it to my node ? (noob question I guess ... but I don't want to burn my node
)I have found the answer myself with the schematic
Have you ever tried to power the node with 1 x CR2032 battery ?
I have tried, but the node doesn't send anything further than 5 meters ...
-
I would like to know if your nodes are working all fine. I have the problem that my nodes freeze after a day or sometimes after a week.
-
@siod my temperature nodes work good, but my relay one doesn't work
Do you have any logs when it freezes ?
-
@carmelo42 no, unfortunately I don´t have any logs, any idea how to create logs?
-

maybe if you keep your node connected to your computer with USB to serial adapter ?
-
mmh, no, that would mean I would have to run my computer for maybe 2 weeks 24/7...
I guess it has somehting to do with the sleep function, the device seems to nat wake up after a while for some reason
-
So i got the boards and build them and they work perfect.
One thing i couldn't figure out is why do i get relatively high current consumption, when the node is sleeping i get 1.5mA and not 5.8uA as in mentioned in this post.
I use 8MHz internal clock and the sleep function and nothing is connected to the node.
Can someone help?
-
@dpressle Can you post the sketch?
-
Thanks, i see its 6.8 uA now, i had something wrong with my measurements
-
It took me a while, but I just figured out how to get a bootloader burned onto the chip and I'm ready to make my slim nodes! Which board type in Arduino IDE do I use to program the chip once I'm using the 6 pin header after it's installed in the PCB?
-
@JonnyDev13 Make a new board type by editing "boards.txt". There's an example in the first post.

Hi there! I need to buy some PCBs on Dirty PCBs but the URL http://dirtypcbs.com/view.php?share=13847&accesskey= seems broken. Any ideas? Thanks!
-
@รอเรือ Apparently they've moved to a new site. Perhaps you can try this link: http://dev.dirtypcbs.com/store/designer/details/m26872/663/myslim2aabatterynodepcbv2-0panelized
I think you must have a user account and login first. Please report back if it's working or not.
Edit: Wrong link the first time.
-
Thanks @m26872
That link didn't work either. However, by browsing all the shared PCBs I found this URL That link is accessible without logging in first.
Cheers

@รอเรือ Thanks a lot! All links are now changed.

Hey im building my first slim node and i wonder if someone has a sketch for 2 reed switches? i have found the sketch for only 1 reed switch in this thread. Im going to use it for my mailbox. How long do u think it can run on 2x aa batteries?
Do i have to add 2x 10M resistors? or doesnt it work with external resistors then using more then 1 reed switch?
-
@Eawo The example sketch should fit your needs. link Change the pull-ups activation to Low if you use external ones.
I'd expect battery life 5-10 years depending on things such mailbox opening frequency, use of heartbeat signal, battery self discharge and climate.
-
@Eawo Using internal resistors will only give you a few months battery time. One external pull-up for each switch will work and 1M resistors or any arbitrary "high" value is just as good.
-
Thanks
ok now my problem is uploading the sketch it wont work on 1mhz bootloader i tried both a and b hex and the 2 diffrent Board.txt.
I get it to work with the 8Mhz breadboard bootloader.
But then using 1mhz bootloaders it always timesout
-
after a few hours frustration i went donwstars grabbed 2x new atmega328p breadboards and wolla everything works :). I Think i burned my first to putting them in the socket wrong.
-
i have wired everything but it wont work for me
i have solder the 2 reed switch from gnd to d2 and gnd to d3. and ive done the same 2 1m resistors. I can see the node in domotics but no activity then i open and close.
-
@Eawo
The reed switches need to sit between GND and D2 or D3 as you have connected.The 1M pull up resistors need to connect between Vcc and D2 or D3.
This way D2 or D3 are electrically connected to Vcc when the switches are open (pulled high). When the switches close, D2 and D3 get connected to GND.
-
I only come down to 12µA with one reed switch, 1MOhm pullup, 1Mhz bootloader and the binarySwitchSleepSketch. Measured with two different multimeters. This is nearly ten times higher than in the first posting. Changing all internal pullups to LOW doesn't change anything.
Is there a way to optimize the power consumption or is it "good enough" ?
-
@rollercontainer For sub 8uA consumption you need to go to "deep sleep" where the internal timers of the processor are disabled. Only wake up on interrupt.
sleep( interrupt1, FALLING, 0);
-
@rollercontainer - I just build a slimnode and 13uA is without anything connected what i can reach as well.
For comparison i aim below 100uA when i do this with pro mini and they last around a year with 2xAA so my guess is 13uA is good enough.
-
@sundberg84: Thanks, so I will stick to my 12µA
@AWI: I am using sleep with Interrupt as in this example:
sleep(PRIMARY_BUTTON_PIN-2, CHANGE, SECONDARY_BUTTON_PIN-2, CHANGE, 0);
-
@rollercontainer Your sleep looks good. Did you remove this piece of code?
// Activate internal pull-ups digitalWrite(PRIMARY_BUTTON_PIN, HIGH); digitalWrite(SECONDARY_BUTTON_PIN, HIGH);Take a look at this thread for a < 1 uA consumption...

Since a few months I am very interested in Mysensors and this PCB. I have ordered the PCB and components to build some sensors as for a home security system. For experimental purpose I build one on a breadboard and that is working fine.
A few days ago I started to solder the components on the PCB. The firs one is working fine, but the next sensors have an issue with the transceiver. After 3 boards failing I soldered one without the transceiver. Then I tested it by holding the transceiver at the board and it was working fine. After soldering the transceiver again a not working board.I tested one board by pressing another transceiver on top of the soldered one and I saw some communication in MYSController. The ATMega is still working on the breadboard. The PCB and Breadboard are powered by the same batterypack.
Before soldering I tested all the transceivers with my breadboard and they are working fine. I am also using an anti-static bracelet.
What am I doing wrong??
-
Have you desoldered one radio to see if it's back alive again? What's your distance to Gateway? Maybe some filtering or antenna effect by your fingers and breadboard? What if you leave a working radio on the breadboard then just connect it with wires to PCB?
-
@m26872
Distance is about 50cm. They are both on my desk. If testing then I do not tough the sensor. Just when trien pressing a radio an a non function radio.
I tried to de-solder the radio but did not succeed. Cut the pins, removed them and soldered wires to it. Connected to a new radio. Strange part is that the on very irregular basis message are received in MYSController. Also with a radio which is functioning well on the breadboard
-
@aneco - 50cm is a big problem for me! Its to close and the node - gw is having a hard time communicating for some reason. I wish I didnt set my gw up in the workplace where i build because every time im testing some node I have to go to the next room. Maybe you could try this?
-
@m26872 - I made this (but with the big motiondec, because my small ones didnt work so well due to clone/copy). Thanks for PCB, instructions and tutorials. Great work!
Node is running at 13uA without motiondetector attached and 90-95uA with the motion dec attached. Im happy with that and ill see how long the batteries last. When my small motion dec arrive I can just switch over.
-
@sundberg84
The node on the breadboard is on the same desk and same distance to gateway. The same for my first sensor. And both are working well. Only issue with 4 sensors a soldered afterwords.Just remember now that I used for the first sensor other solder. But do not think that this is causing the issue or .....
-
Hello i wonder how you do then you put sensors outside mine stop work after a few hours i guess its becouse its cold here and maybe humitiy? then i take them inside for while it start working again. i think i need a waterprofe case or something
-
Well, batteries and components have working temperatures so it depends how cold it gets over there
-
Its one in the garage it is never below 0- C this one was alive the longest the other one was dead in 2-3days and maybe as coldest it was 10- C. I'm starting to think it's something wrong with the gateway
-
If you reset either node or gateway, does it go back to work or what?
-
No it doesn't only sometimes
-
If it was the gateway you should stop receiving data from other sensors too, right?

@AWI said in My Slim 2AA Battery Node:
@rollercontainer Your sleep looks good. Did you remove this piece of code?
// Activate internal pull-ups digitalWrite(PRIMARY_BUTTON_PIN, HIGH); digitalWrite(SECONDARY_BUTTON_PIN, HIGH);Take a look at this thread for a < 1 uA consumption...
Hmm, I noticed, that I have to disable the internal pullups. But instead of removing the lines, I set them to LOW. I will test it without the lines and come back. Thank you @AWI.

Ok, just want to give you an update:
I have 3 sensors running in the moment, initially I planned to run a lot more, but I still have problems with freezing of the sensors. The Sensors ran 2 months now until they were not coummunicating anymore, 1 is still working. I restarted 1 of the freezed sensors and it just came back up and works fine again, I leave the other one "freezed" just to see if it would come up again...
It´s sad that they are not very reliable but I don´t get what makes them freeze after working quiet good for such a long time (they are reporting every 15 minutes 24/7 and whenever a window is opened/closed).
I don´t think it´s a temp thing, also power should be no problem, batteries are still about 80 % loaded...
-
Maybe there is something like a counter (variable++) which causes a overflow after two month?
