Description
The device is used to measure the soil moisture by measuring the resistance, compatible with Arduino and Raspberry Pi. More water makes the soil better conductive (lower resistance), if the soil is more dry, it's conducting the current less effectively (higher resistance). Supply voltage is from 3.3 V to 5 V. The sensor is equipped with a Gravity connector.
