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 5VWorking current 20mAWorking temperature 40 85 ℃Interface definition XH2 54 3pin GND VCC Singal Communication signal analog signal outputSize 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 Package Included 1 x Soil Humidity Sensor Module for pyboard MicroPython Programming
