Copy links for more details:

A LG 3000mAH 18650 battery could make ESP32run 17 hours or more.

This capacitive soil moisture sensor differs from most of the resistive sensors 

on the market, using capacitive sensing principle to detect soil moisture.

 It avoids the problem that the resistance sensor is easy to corrode and greatly

 prolongs its working life.
