@Dylano

you cold try to modify this sketch:
https://github.com/n3roGit/MySensors_n3ro/tree/master/in_process/Multisensor_PIR_DHT_light_switch_battery
its not finished but there is all you need

@Dylano the sketch send the battery percentage everytime the voltage is changed

@Dylano what do you mean with long readVcc?

The battery life is different because of the frequency of triggering from the pir.

Some nodes works for 2 month. Other ones for 6..

@Dylano

But I don't use the dht anymore.
https://github.com/n3roGit/MySensors_n3ro/tree/master/Multisensor_PIR_SI7021_LDA_Battery

This works much better!

@Dylano
Hey,
Yes it works very good with 2 aaa Batts.

You can find the read library here

https://github.com/sweebee/Arduino-home-automation/tree/master/libraries/readVcc

@hek whats this??

Hey folks,

what's the correct way to use repeating nodes?

I have build 3 usb powered LED-Lights and one of them is out of range...

Is it a good idea to enable repeating on every USB-powered node?

https://github.com/n3roGit/MySensors_n3ro/blob/master/moodlight_extended/moodlight_extended.ino

gw.begin(incomingMessage, NODE_ID, true);

@Anticimex like homeduino with:

sudo apt-get install arduino-core avr-libc avrdude binutils-avr gcc-avr libconfig-yaml-perl libftdi1 libyaml-perl screen python-serial
git clone --recursive https://github.com/pimatic/homeduino.git
make upload

yeah!

is it possible to update the gateway via shell?

@dakky Yes, this is because of the multiple sensors on my board. maybe somebody have more tuning tipps.

@dakky said:

1500uA

The sleeping current is ~240uA.

But it's possible to tune it a little bit more.

i hope i can buy this board in the near future

@riataman said:

with a 5v arduino

Hey
the operating voltage of this component is 1.9 to 3,6 v. not 5v

But the idea to remove the regulator to save a little bit energy is cool. i will try it

@icebob hey the used pir consumes ~50uA. Since my last modifications I replaced the stepup and the dht with a si7021 sensor and the external pullup with 1m ohm. Now the sleeping current is ~190uA

https://github.com/n3roGit/MySensors_n3ro/blob/master/Multisensor_PIR_SI7021_LDA_Battery/Multisensor_PIR_SI7021_LDA_Battery.ino

What do you mean with you recommenced sensors?

Jeah this is very cool!

My Idea is to change the sleep time when iam not at home or in the night.

Do you know the release time for 1.6?

Hey folks,

is it possible to queue commands on the gw to send it to the node later (like zwave)?

cenario:
1x battery powered node
1x mysensors gw

gw send "turn light on" to node (queue)
node is in deep sleep...
...
...
node wakes up and connect to the gw
gw transmit "turn light on" to the node
...

regards
n3ro

@tbowmo
why i cant see the debug information "ratio failed" or sending commands if debug is only enabled in the sketch?

Perfect

// Enable debug flag for debug prints. This will add a lot to the size of the final sketch but good
// to see what is actually is happening when developing
//#define DEBUG

Yeah. now the new node works and the sleep current is about ~240aA.

But i still not understand why i get debug outout on serial if debug isn definded^^

@m26872 said:

You also have the "define DEBUG" in the mysensors config-file. Is it that serial output you're referring to?

Yes the serial output. whats to do to put it in the mysensors config?

@m26872 said:

#define DEBUG

btw. this #define DEBUG is a very cool idea!!!

But i get a serial output if DEBUG is not definded

Big THX,

now i have understand how to use the si7021

Reading works great!

But the sleeping current is very high ~1500uA

Thx for the comment. Could you explain it a little bit more please? I have seen the the sensorblend sketch

Hey folks,

i have just get some SI7021 modules. Now i want to replace all DHT sensors in my nodes with it.

But my problem is, that i dont understand how the si7021 is wired (PINs to read?) and used in the sketch.

old DHT sketch

https://github.com/n3roGit/MySensors_n3ro/blob/master/Multisensor_PIR_DHT_LDA_Battery/Multisensor_PIR_DHT_LDA_Battery.ino

new one with si7021

https://github.com/n3roGit/MySensors_n3ro/blob/master/Multisensor_PIR_SI7021_LDA_Battery/Multisensor_PIR_SI7021_LDA_Battery.ino

Any tipps for me?

regards,
n3ro

Maybe its broke.... The China stuff is not everytime the same quality

Do you have another one?

me too

@GertSanders said:

(0.8V <-> 9V)

Yes. I had a few problems with the 5v PIRs. That's why I ordered this.

@GertSanders
thx

I have just ordered some SI7021 for testing.

My Pir sensors are these ones:
http://www.amazon.de/gp/product/B008EGH3FM

50 Mikroampere

i dont know if this is aktive or passiv

Hey togehter,

is a battery drain graph like this normal with alkaline batteries?

regards,
n3ro

This sounds great!

Do you have a code example?

@Suresh-Mali My sensor node is powered with two AAA Batts. Over the time the voltage drops down to 1,9v.

The DHT only works with ~3v. so i need the stepup only to power the dht

i use this setup with my multisensor nodes.
http://forum.mysensors.org/topic/1514/multisensor_pir_dht_ldr_battery/3

Without transistor the battery is drained in ~2 month (black line)
with transistors in ~10 month

Hey folks,

I have just tried to reduce the sleep current of the nodes. With

*a transistor to turn on and off the stepup
*a second transistor to disconnect the ldr
*a external pullup with 680k for the pir

Now I have a sleep current of 220-240uA.

Any ideas to tune it a little bit more?
Is it possible to check if the node is wake up from the interrupt or the timer?

Regards
n3ro

@ht81

hmm the max voltage of the NRF is 3.6v (https://www.sparkfun.com/datasheets/Components/SMD/nRF24L01Pluss_Preliminary_Product_Specification_v1_0.pdf)
maybe the NRF is broker after 3.7v. i dont know...

the 2N2222A turns the stepup on and off. the DHT is direct connected to the stepup.

you can read many stuff about the power consumption of NRF+Arduino in the forum. With modified fuses and cutted LED+power regulator ~40uA

@Harrdy the stepup with 5v output is much cheaper

i have only a test setup at the moment with 2 AAA batteries. So i cant give you a battery lifetime

I use a arduino 3.3v and the stepup pushes the voltage to 5v for the DHT.

I use this setup at the moment and it works. the arduino is still alive

@ht81 Hey, the NRF is directly connected to the battery. only the DHT use the stepup.

i use this stepup: http://www.banggood.com/2Pcs-500mA-DC-DC-1V-5V-Converter-Step-Up-Module-Power-Module-p-945167.html

Just put a transistor in front of the stepup. this is all

@Ashley-Savage

No problem. I make one give me a day

@f1dev sweebe wrote a very good howto:

http://forum.pimatic.org/topic/383/tips-battery-powered-sensors

I think you need the irq only for the gw. I have a receive node without irq.

Do you have changed fuses on your arduino?

And remember. All this stuff is cheap China electronic.The devices can vary consume a lot of electricity.

@BulldogLowell could you please explain your changes? I don't understand everything of this

@f1dev yes. But you don't need irq on a node

@Moshe-Livne just deactivate the this lines:
//digitalWrite(MAILBOX_FRONT_PIN, HIGH);
//digitalWrite(MAILBOX_BACK_PIN, HIGH);

and solder two resistor from 3.3v to pin 2 and 3.

it is fixed changed internal pullup to an external with 680k. now its 32uA with both opened and 47uA with both closed

Thx for the tips. I will try it.

I have just measured the current:

32uA in sleep and both opened
when one reen switch is closed: 171uA
when both closed: 309uA

i use a internal pullup and dont know why the current is so high when switch is closed

hmm after some days testing it works very fine, but:

the battery drains very fast and in dont know why. The Arduino sleeps the whole time and wakes up when the postman is coming (maybe 2 times a week).

The battery drains 11% in 7 Days

Any Ideas?

The power LED and regulator is cutted and the fuses are modified.

Regards
n3ro

@Didi fixed

@Didi und wie heißt das verdammte teil auf englisch?

Okay But at the moment its fixed only freestyle

Just finished my new project.

I have added two magnetic switches to the front and the back of my postbox. Now i get a Mail if the postman was here

You need:
1x Arduino Mini Pro 3,3
1x Battery Holder (2xaaa)
1x NRF
2x Reed switches (http://www.reichelt.de/KSK-1A663-2025/3/index.html?&ACTION=3&LA=446&ARTICLE=151700&artnr=KSK+1A663+2025&SEARCH=magnet+schlie�er)
2x magnets (http://www.reichelt.de/MAGNET-M4/3/index.html?&ACTION=3&LA=446&ARTICLE=12483&artnr=MAGNET+M4&SEARCH=magnet)

And this or a similar sketch: https://github.com/n3roGit/MySensors_n3ro/tree/master/Mailbox_Alert

It works great

i dont understand how to use this...
Can somebody explain it?

Yes. This is a step up with a transistor for the dht.

I want to reduce the battery drain with the transistor.

http://forum.mysensors.org/topic/1446/battery-sensor-with-stepup-and-on-off-transistor

Hey Guys,
Today I have completed my first multisensor.

As base I used a cheap china fire detectors and the MYS PCB board.

http://www.ebay.de/itm/like/Optisch-Feuermelder-Rauchmelder-Funkrauchmelder-Rauchdetektor-Rauchwarnmelder/141252448370?hlpht=true&ops=true&viphx=1&_trksid=p5197.c100068.m2280&_trkparms=ao%3D1%26asc%3D20140211130857%26meid%3D07bc95de38bb49768007aea7e82e859d%26pid%3D100068%26clkid%3D6724945852786999307&_qi=RTM2052467

All components fits very well in the housing.

Unfortunately, the modified HC-SR501 do not work well with <= 3V with the DHT (delay in the sketch). Now I use this:
http://www.amazon.de/Niederspannung-PIR-Infrarot-Bewegungssensor-erkennt-Modul/dp/B008EGH3FM/ref=sr_1_1?ie=UTF8&qid=1433801387&sr=8-1&keywords=B008EGH3FM

And it works very great!

The used Sketch is this:

https://github.com/n3roGit/MySensors_n3ro/blob/master/Multisensor_PIR_DHT_LDA_Battery/Multisensor_PIR_DHT_LDA_Battery.ino

wiring diagram coming soon;)

Hey

What size are the SMD resistors and stuff?

@ServiceXp could you already test cold start vs sleep?

@ServiceXp is use this: LINK

@hek In my tests its working with DHT11 and DHT22. Maybe a MQ-2 works too, but a MQ needs 2 minutes heatup time..

Jeah now its working

#include <MySensor.h>
#include <SPI.h>

#define SENSOR_INFO "Test sensor"
#define NODE_ID 200
#define CHILD_ID 1
#define OPEN 1
#define CLOSE 0

MySensor gw;
MyMessage msg(CHILD_ID, V_TRIPPED);

int repeat = 0;
boolean sendOK = false;
int repeatdelay = 0;

void setup()
{
  gw.begin(NULL, NODE_ID, false);
  gw.sendSketchInfo(SENSOR_INFO, "1.0");
  gw.present(CHILD_ID, S_DOOR);
}

void loop()
{
  resend((msg.set(OPEN)), 5);
delay(500);

}
void resend(MyMessage &msg, int repeats)
{
  int repeat = 1;
  int repeatdelay = 0;
  boolean sendOK = false;

  while ((sendOK == false) and (repeat < repeats)) {
    if (gw.send(msg)) {
      sendOK = true;
    } else {
      sendOK = false;
      Serial.print("FEHLER ");
      Serial.println(repeat);
      repeatdelay += 250;
    } repeat++; delay(repeatdelay);
  }
}```

Hey Guys,

Today I had an idea how you can save some power on battery sensors.

I simply connected a transistor before a StepUp converter. So the stepup and the connected sensors only supplied with power when they are needed.

My stepup + DHT11 has power consumption at 90 uA when sleeping. By disabling with the transistor it goes against 0.

Do you think that might help a little?

@rickmontana83 said:

put the gw.send() call in gwack() and pass the msg value as a reference/pointer to gwack.

What do you mean?
Like this?

void loop()
{
//gw.send(msg.set(OPEN));
  gwresend("msg.set","OPEN");
  delay(500);
}
void gwresend(char msgcode[],char option[])
{
  int repeat = 0;
  boolean sendOK = false;

  while ((sendOK == false) or (repeat <= 10))
  {
    if (gw.send(msgcode(option)) // execute code
    {
      Serial.println("OK");
      sendOK = true;
    }
    else
    {
      Serial.println("NOT OK!!");
      sendOK = false;
    }
    repeat++;
  }
}

(code is not working )

I'm very surprised that there is not already such a function.

Has someone tested a piezo-buzzer (or summer) with arduino?

i want to use THIS Buzzer for my low voltage sensor. But don't know if this is a matching component for arduino.

Hey

I have just build this test function to resend a signal if failed.
But i don't know how to execute the ge.send in the string ("// execute code").

#include <MySensor.h>
#include <SPI.h>

#define SENSOR_INFO "Test sensor"
#define NODE_ID 200
#define CHILD_ID 1
#define OPEN 1
#define CLOSE 0

MySensor gw;
MyMessage msg(CHILD_ID, V_TRIPPED);

{
  gw.begin(NULL, NODE_ID, false);
  gw.sendSketchInfo(SENSOR_INFO, "1.0");
  gw.present(CHILD_ID, S_DOOR);
}

void loop()
{
  gwack("gw.send(msg.set(OPEN));");
  delay(500);
}
void gwack(char code[])
{
  int repeat = 0;
  boolean sendOK = false;
  Serial.println(code); // string to execute

  while ((sendOK == false) or (repeat <= 10))

    }
    else
    {

      sendOK = false;
    }
    repeat++;
  }
}

Any ideas?

@rickmontana83 YEAH!!!!! This has fixed my problem!!

Now i have much better rage with my nodes

Big THX!

@AWI you are right. i get this on the GW:

<- I_LOG_MESSAGE 0;0;3;0;9;send: 0-0-10-10 s=5,c=1,t=2,pt=0,l=1,st=fail:0
-> Sending 10;5;1;1;2;1

<- I_LOG_MESSAGE 0;0;3;0;9;send: 0-0-10-10 s=5,c=1,t=2,pt=0,l=1,st=fail:1
-> Sending 10;5;1;1;2;0

It is possible that the node only accept the switching signal in the "right" moment?

@AWI do you have code example for me?

@AWI cool!
Now it works but i cant switch it off every time. i have to stitch it on and off again multiple times to deactivate it

Hello everybody,

has anyone built a function that resend the signal, if "st=fail" is detected?
I've already looked at the API and ACK. But have become not really smart of it.

This would be great for some devices like relay, alarm, ....

Best Regards,
n3ro

@Jan-Gatzke

Yes, i want to disable the Smoke alarm, because sometime i make really much smoke in the kitchen without any fire

Hey
Sorry my question wasn't good.

Let me explain what i mean.
I have just updated my sketch in Github to make i a little bit better to understood (there is no z-wave component).

I want to Build a USB-powered-sensor with the following functions:

1. Read some Sensors every x Seconds (done with millis and working)
2. Read a PIR (done and working without interrupt)
3. Read AirQuality (implemented but never tested because i haven't this component at the moment)
4. If Smoke is detected make alarm with beeper (same like the AirQuality Sensor)
5. a switch to disable the beeper (i don't know how to implement this)

I hope it's better to follow.

Regards,
n3ro

Update:
This is the beeper

Hey Guys,

I want to build a USB-powered-sensor. I need to change an internal variable per switch. There is not a pin to be driven.

link to sketch

I have not yet understood how the interrupt and the time for reading the sensors is maintained. is that even possible?

Regards,
n3ro

@rvendrame yes i think so. but now its ok

i have still a band range. next i will test a gw with a nrf antenna version. i hope this helps

https://github.com/n3roGit/MySensors_n3ro/tree/master/MotionSensor_DHT_light_battery_mod

now its working. when i use PIN4 for DHT.:)

@BulldogLowell the wires are OK.

In sleep the DHT cant warm-up. so the dht need 2 sec before read. when i dont use the delay i cant read it.

i dont understand why the interrupt didnt work with the enabled delay.

do you have tested on a arduino?

@BulldogLowell
when i use this sketch the PIR works but the DHT cant read:

Failed reading temperature from DHT
Failed reading humidity from DHT

i think millis didnt work with sleep. the counter is not increasing when sleeping..

@BulldogLowell

Hey, its a good idea to send only PIR if changed!
The unused code in the sketch is because i have reduced the used functions to the minimum to debug it better. The full sketch has LDR and battery lifetime output too.

i have added some extra output in the modified sketch:

@Sweebee thy this would be very nice

You find my sketch here:

@n3ro said:

#define PIR_SENSOR_DIGITAL 3

@rvendrame in my last test the pir sends endless 0 and dont sleep

@Sweebee
is #define INTERRUPT PIR_SENSOR_DIGITAL-2 wrong?

when i use a switch it looks OK

if i use this

The DHT gives only output the first start and the pir interrupt works perfect.

When delay(dht.getMinimumSamplingPeriod()); is activated the DHT works and the pit interrupts the whole time
In this configuration the arduino never sleeps ..

EDIT: i have changed the sleeptime for testing to a shorter time

@rvendrame The DHT is on pin 2 and the pir on pin 3. i use the MYS PCB.

i suspect the delay function disturb the sleep function. if i dont use the delay, the dht cant "heat up".

far as I know the interrupt is only an internal value. right?

the pir works fine. but the dht doesn't work.

when delay(dht.getMinimumSamplingPeriod()); is used the dht works and the pir fails.

@rvendrame do you have an idea how to do it?

I have a idea,

is it possible to build a second loop like this?

can somebody help me with my sketch? i dont understand millis

ufff. to build a multisensor sketch is really hard

thx for your info!
