Hygrometer Detection Soil Moisture Sensor Protection Board Buffered output drivers to connectThis is a simple moisture sensor can be used to detect soil moisture, when the soil water, the sensor output of the analog value will be reduced, and vice versa will increase. Use this sensor to make an automatic watering device. When you are not at home or after a long time, it can sense if your plant is already thirsty. To prevent the plants withered to know that is caused by water. With the Arduino controller to make your plant more comfortable,
