mmmm i think that al this work, for a 4 weeks working sensor is not a good solution for a home automation system....
Why can a Zwave or 433Mhz motion sensor work for more then a year...
Is my biggest question..

Is there relay now solution for a battery live for a year...
Other bord, other sketch, other regulator, other battery...

or...

My motion sensor has dropped 2% battery level during last one month. It's in a busy area (sends ~200 messages per day).

Yes i see your very nice project...
Only i am a amateur and can not [ yet ] build your nice sensor ..[ i wiill try when i have the stuff ]

Only what is making your sensor so great..
The software or the hardware??
When i use your sketch, is my sensor then working for a longer time?
Because the size is not my problem.. [ i will try to build build a my sensor in a factory motion sensor, that will fit ]

Dear all.
I have built a few sensors, on battery.
Everything works but only for a week or...
I have a nano with just a motion sensor and a sleep time of 15 minutes
Sketch

With a battery of 3000mAh block @ 5 volts.

I have a small pro on 3.3volt @ 2x 1.5 volts with a power up for my motion sensor


Sketch
All LEDs and the power regulater removed.
Only a motion sensor, with sketch sleeptime 20 minutes.
Quiet area for a week or
...
Why can operate a Zwave or a 433Mhz motion for months / years on 3xAA. And a powerbank and a mysensor less than a month?
Does anyone have a solution

I think i go wrong... Only where??

Thanks for all the help!!

guess what...
I do have a:

Exact the same board in of this light...
I think i going to try the make this work...

Only i do not understand exact the wiring of your example.
Will you please make a list of exact stuff to buy.
And make some more pictures, from the good places..

And a thing that i see.
You use D2 from the arduino.
Is that not a one for the radio?

@Elfnoir

This is great.....[ and great for a dummy like me ]
Would you please tell me all the hardware you use?
Or the strength of the resistor etc etc

@GertSanders

This option with a pir...
or a magnet sensor.
What is the battery live?

I wait..
Hope you give a signal here when there are new possibilities..
And i hope you will share a stable sketch... for battery devices.

good luck!!

mmm i ordered 1...
So i hope i gonna ix this...
It is looking higher mathematics

Will see... when i have time..
Thanks for the sketch!!!
Give it a try in a uno ...

D203s pir sensors

Can i buy his board?

higher math for me...
Great...

Can you use the motion seperate from the liight?
And can u use the light with a switch option? [ i will turn on the light when there is motion.. ]
Or is the light switching only on lux?
