3 in 1 incl battery monitor

[carlierd]

The error is because I enable the signing function !
Remove the following line:

MySigningAtsha204Soft signer;

And replace

MySensor node(transport, hw, signer);

by

MySensor node(transport, hw);

I don't know who had the best sketch.
I measure internal battery status using the 1.1 reference.

When i put this sketch in to a nano..
With a 9volt battery....
How long do think this working?

Or how long is this acting on your 3 volt battery's?

[carlierd]

It depends on the activity close to the sensor so not possible to say but some people reach several month without problem.
In my house it's very fresh so I have not a lot of feedback to give.

5 days....:-1: on a 9volt block
The sketch on a nano
On my toilet.... so not a very busy room

Is there some one that live longer, with this sketch......?

@the-cosmic-gate Nothing special. I made a big sketch, which contains 7-8 sensors (DHT, Si7021, MQ-2/9, PIR, Door magnet, Light, battery) reading code because I would like to upload the same sketch to all nodes and configurate it on controller side, which sensors is on the node and need to read.
But currently I reached the limit with I2C includes, so I need to think over this solution.

Dear..
Did you finish your big code....

Hello,

9v means that you are using a voltage regulator which probably consumes a lot of power.
Why not using AA or AAA battery directly connected to Vcc ?

Motion and DHT needed 5volt i wash thinking..?
So 9 @ the vcc should be strong enough i was thinking.
And i do have @ the same time 3.5 for the radio

Are the extern step up better than the step down on a nano?

[carlierd]

The motion can be adapt to run on 3v easily (connect the Vcc to the H pad if available. You can find information on the forum). The DHT could also run on 3v. I have several nodes like that. No problem.
Can't reply for the step-up because I don't use it.

@ David

How long is the 3v battery running whit this option?

[carlierd]

@Dylano : My nodes are really new so difficult to say exactly but for the moment the oldest node was started one month ago (04/02) and battery still at 3.32v.

i'am back in business after the "big move" and going to try again to get this 4:1 sensor working for a long time uning 2 x AA batteries.
If someone has some new input, please let me know :) and feel free to change the sketch

[carlierd]

@the-cosmic-gate
Hello,
Motion nodes are still working correctly. The oldest node started the 4 of February is still at 3,29v. My other nodes (temp / humidity / light) are also working correctly but I will replace DHT22 for another sensor.

David.

Hey @carlierd Just curious if you are still using a DHT22 with your sketch? Have you modified the code much from the above? I am looking at implementing something similiar ( identical actually ) and was wondering if much has changed for you over the last few months?

Thanks!

[carlierd]

Hello,

All nodes are still working correctly but I still want to replace DHT22. But nothing done for the moment. Not at top position on my todo list ;)
