How to wire battery sensor with battery voltage reports...

Hi!

Ok, i wanted to share my "sollution" or atleast current setup if someone else in the future has the same problem.

The radio and battery voltage sensor (R1/R2) is not connected to Step up regulator.
Also DHT22 sensor needs atleast 3v to operate so i put the arduino and DHT22 after the voltage regulator.

Im sleeping the node for 15min, then sends temp and hum. The Battery status is sent each 8 loop. Now i will have a look how fast the battery is drained. I have not removed the led in the aurdino or step up reg so im guessing quite fast.

I have the radio about 15 meter (1 wall) from the gw - 100% seems to be st=ok.

Any improvement ideas - let me know,

Hi all, I'm newbie with these libraries.
And I'm a bit confused about the picture.
I'm guessing is that the picture still similar with the battery page in build sites. What makes me confused is that resistor position. And also what is the source to measure in the voltage divider? Is it vcc?

And also, is it correct to take power directly from the batteries instead from the arduino itself?

Im a newbie as well, also a bit on and off building...
Yes, i have tried to work from the battery build site. I saw you did a own post about this and worked it out.

1. I have also tried to take power to the radio from the booster - but this seems to drain the battery very fast, annyone else experienced this?

2. Also i tried to take power to the radio from the arduino - and it works well, is there any downsides with this?

3. Is the radio using any power not used? It seems like the battery last longer with the radio connected to the arduino instread of the battery. When the arduino sleeps - so does the radio i guess, but does the radio sleep any time connected directly to the battery?

Would be awesome if you made a fritz sketch of this :)

@ronnyandre - hehe! That was a while ago :)
I even made a PCB for everyone to use (including full schematics)!
