Before I used ESP Easy on the AI-Thinker board.
Now I am trying to reduce battery consumption by using youre .ino.
While compiling i’m getting the following erros.
Can you help with this subject??
Error:
thingspeak-data-logger:15: error: ‘DHT11’ was not declared in this scope

Thanks for reading and replies.

With regards.

With this the board could theoretically survive more than two years in permanent deep sleep. This experiment will show how much the wake-ups costs and if theory es even close to reality. 8x batteries

I was reading migth be some problems, due the voltaje of the pins 3.3v to feed the sensor. Have you noticed alike?

The graphs at least on the cellphone appear in white . have the bateries died?

Kind regards
-Alex

Heyyy
thanks again rsrsrs
are there a kind f sleep where i can wake up in the main loop ?
sorry for the inconvenient

Hi Tugao
This is completely normal and intended. When going to deep sleep the ESP basically turns everything off except the timer that you might have programmed to wake it up again…

Cheers,
Dani

It could be interesting to see how low it is
