Description

This soil moisture sensor has two probes through which current passes in soil, then read the resistance of soil for reading moisture level. We know that water make the soil more prone to electric conductivity resulting less resistance in soil where on the other hand dry soil has poor electrical conductivity thus more resistance in soil. Using these properties of electricity the sensor is designed. Inside the sensor there are circuitry for measuring the resistance and converting it into voltage as output.
