[SOLVED] Arduino Nano with SIM800L and DHT11 on batteries

Hi,

I am trying to run a project on batteries with NANO and gsm sim800l. The purpose of the project is to display the temperature in a room with blynk (History graph). I want the arduino nano to sleep most of the time and sim800L to be powered off and only 2 to 3 times a day arduino will wake up power on the sim800l and send the temperature.

I tried with some sleep options in arduino but i failed. Can you please advice?

Hello and welcome to the Blynk Forum.

We havenโ€™t a clue what you have tried or how/why it failed, so not easy to advise.

Have you tried searching this forum for other battery powered projects, topics, ideas, etc?
