QB072 Moisture Sensor

Soil moisture sensor is a sensor used to detect soil moisture, which can sense the soil condition in time to make plants grow better. The soil moisture sensor is to insert two probes into the soil, and then as the current passes through the soil, the sensor obtains the resistance value by reading the current change between the two probes, and converts this resistance value to the moisture content. The higher the moisture (and the less resistance), the better the conductivity of the soil. Therefore, if the soil is short of water, the analog value output by the sensor will decrease; Otherwise, it will increase. Application reference: smart agriculture, plant research and other scenarios that need to sense soil moisture.
