Soil Moisture Detection Sensor

The soil moisture sensor is a device that can be used to measure the moisture level in soil or the level of a liquid on a small scale.

The moisture measurement probes are used by inserting them into the medium to be measured. Due to the resistance created by the soil or the liquid in which the probes are inserted, a voltage difference occurs between the probe tips. The moisture level can be determined based on the magnitude of this voltage difference. As the moisture content in the soil increases, its conductivity also increases. Sensitivity can be adjusted using the trimpot located on the board.
