Soil Moisture Sensor Auto Watering DIY Kit for Arduino

This module is a simple moisture sensor that can be used to detect soil moisture. When the soil is short of water, the sensor output value will decrease, and vice versa. Use this sensor to make an automatic flower watering device, which can be used when you are not available for a long time. At home or after the watering time, it can sense whether your plants are thirsty. Prevent the plants from withering before you know it is caused by lack of water. Cooperate with the Arduino controller to make your plants more comfortable and your garden smarter.
