Soil Humidity Sensor Module for pyboard MicroPython Programming Learning Development Board

Overview: The soil moisture sensor is a simple moisture sensor that can be used to detect soil moisture. Based on the principle of different resistivity changes of soil moisture, the sensor can be inserted into the soil to output continuously changing analog values to reflect the soil humidity. When the soil is short of water, the sensor output value will decrease and vice versa. Specifications: Power supply voltage: 3.3V-5V Working current: <20mA Working temperature: -40-85 a Interface definition: XH2.54 (3pin: GND, VCC, Singal) Communication signal: analog signal output Size: 20.4 * 66mm Applications: Using the characteristics of the soil sensor can cooperate with the microbot to make a simple automatic watering device. When you are not at home for a long time or the watering time has passed, it can sense whether the plant needs watering, to prevent the water shortage. The plant withered.
