Sensebender Micro

nutcracker

Thanks @hek, I also realised my mistake once I retraced my steps...I hadn't scrolled down fully on that screenshot that shows the Sensebender Micro board... I think what through me is that screenshot also shows a "dot" against another board - the Arduino Micro board...and I was selecting that... duh! (may be worth changing the screenshot? ;))

Anyway, thanks for your help...sketch uploaded perfectly after that!

Ah... there is a dot in the menu-image. Will update it. Thanks.

RJ_Make

@hek Interesting.. I didn't know this.. I used the standard Pro Mini 3v3 and it worked...????

gloob

Received my Micros today. Luckily there was no custom and a lot of pins to solder. Can't wait to solder them on wednesday on work and test them.

Is there any instruction how to solder everything? On which side the radio module needs to be soldered.

tbowmo

@gloob

This might help you out :)

gbfromhb

I hope this question has not been answered already and I did not miss the answer. I was thinking about connecting a motion sensor to this and was hoping that one of the digital pins supports an interrupt. Is there an interrupt available?

hek

@gbfromhb

D3 is available on the side-pins. D2 is routed to the radio but can be used with some hacking.

I'm planning to do the same thing.
i ordered my 5v step up regulators to support the PIR sensor.
although I hope adding the motion isnt going to kill the batteries.

@mvader
I have so far had no problems running my PIR sensors at 3.3v with the following hack.

http://techgurka.blogspot.com/2013/05/cheap-pyroelectric-infrared-pir-motion.html

You can not do this with all PIR Sensors from what I understand, but one of the ones listed in the MySensors store is what I've been using. Go down to the bottom of the article.

gbfromhb

@Hek
Thanks, I saw the D3, but I'm new enough to this adventure that I was not sure if I should have assumed that it also had an interrupt like all the other boards.

tbowmo

@gbfromhb

I tried to keep the naming, and pins on the atmega, the same as an ordinary arduino :)

wow.. nice.. thanks for the info! I will give this a go asap.

Hello,

I have one more question. Is it possible to power the micro from the ftdi pins? I would like to use jumper wires.

tbowmo

@gloob

Yes it's possible to power it from the FTDI pins, if you want to..

gloob

Are there any recommendations for a low power temperature, humidity sensor regarding the update cycle.

Currently I plan to wake up the sensor each 10 minutes instead of each 1 minute to update the values. This should increase the duration of the battery. A complete update of all values if performed each 30 minutes as usual.

tbowmo

I would probably choose 5 minutes interval instead.. I have updated the sensebendermicro sketch tonight (just waiting for @hek to approve it). so it holds of on the transmissions a bit. Now the temperature needs to change more than 0.5 degrees from the previous transmitted value. OR
humidity needs to change more than 0.5, measured with a moving average. OR
30 minutes since last transmission.

gloob

I found that when I power the micro from 2 batteries I get the following error:

T: 23.21
H: 50
send: 104-104-0-0 s=1,c=1,t=0,pt=7,l=5,st=fail:23.2
send: 104-104-0-0 s=2,c=1,t=1,pt=2,l=2,st=fail:50

This does not happen when I power it from the FTDI programmer.
Does anybody have any ideas?
The batteries have a voltage of 3.25V

I did not have this issues with my arduino nano sensors. and i did use the same radio modules.

When I check the modules they seem to be real nrf24l01+ modules:

I have a batch of 5 sensebender and actually I build 3 and one of them doesn't work properly. Lot of st:fail when I put my finger on the board it works better so I try to make all solder one more time but it's not ok. I try with few radios and same radios work well on the others sensbender.
Any idea or way to exchange with Itead ?

tbowmo

@Fabien

Where exactly do you put your finger on it, in order to get it working?

tbowmo

@gloob

It's the same power rail (FTDI, and the battery connector). What do you supply the board with, thru the FTDI header?
