Multisensor_PIR_DHT_LDR_Battery

[icebob]

@n3ro Yes, you can. The sleep function has a return value. If it is < 0, timer is timed out. Otherwise it waked up by interrupt.

I'm working on a same multi sensor PCB with batteries. The PIR consumes 150uA. So you can reduce consume if your search a low power PIR sensor. Like this: http://forum.mysensors.org/topic/2387/low-power-pir-breakout-board-for-mysensors-and-evaluation/6
@scalz said it consumes only ~24uA.

@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

@n3ro ohh, it's great. Which PIR are you using?

@n3ro I Mean the sensors advised by the Mysensors store...

@n3ro

Great...
Hope this will work for a long time on a battery?
What battery's you are using?

1 problem< WHERE CAN I FIND:
#include <readVcc.h>

[n3ro]

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

You can find the read library here

@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]

yes i saw your better solution..the si7021 is using less power i read..
Where do i have to place the: long readVcc
And how do ik make that .H file?

How long is the multisensor running? on what battery?

[n3ro]

@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]

sorry, it is working now: what do you mean with long readVcc?
I use the sketch battery pir, to test

Only the report of the vcc how many times is the sketch reading this?
And where can i see the status?
I use Domoticz as controller.

[n3ro]

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

[Dylano]

great, i see in domoticz the value great!!!...[ when power is low i get an alert. ]
You have a lot of sketches :-)
Is het possible that you build a sketch include your pir-battery-ldr, and a light switch, or a option so i can switch a ledlight.
Like a pir-battery-ldr-switch... :-)

I will try to rebuild a solarpowerlight
With a solar powerbank, and a:Light

So i can have a Domoticz controlled solarpower light and motion/ldr [my]sensor
Only i cannot make a sketch for this... [ if you want, i will pay for it..., or a donation to charity organization ]

[n3ro]

@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 ;)
