Hi guys, i want to make an auto watering Arduino powered using solar panel and batteries so the most important is reducing power, i will use a barebone atmega328p and using sleep library to make the board sleep 10 min and wake up for 30s to read the Soil Moisture and humidity sensor.
By the way, i want to ask you :
1- how can i turn off these sensors when the Arduino in sleep mode to reduce the power?
NB: The Current of The soil moisture sensor 35mA.
The current of the humidity sensor 2.5mA
2- Maybe i will add a 1602 LCD, how to turn off also?
