Soil Moisture Sensor

Description

A soil moisture sensor measures the moisture in the soil and similar materials. It has two probes that can be dipped in the soil and the power supply and output terminal can be connected to the Arduino, PLC and other microcontroller boards. The two probes act as a variable resistor which calculates the values from it. If there is more water in the soil the resistance value goes down and provides more conductivity. This leads to calculate the amount of moisture level in the soil. Most customers use this to automatically water their plants and irrigation system projects.
