OverviewSoil Moisture Detection Sensor The soil moisture sensor is a sensor that you can use to measure the amount of moisture in the soil or the level of a small liquid. Moisture meter probes are used by immersing them in the medium to be measured. Due to the resistance created by the soil or the liquid immersed in, a voltage difference occurs between the probe tips. The amount of moisture can be measured according to the magnitude of this voltage difference. As the moisture content in the soil increases, its conductivity also increases. Sensitivity adjustment can be made thanks to the trimpot on the card.
It can be easily used with Arduino or different microcontrollers.
