This is a simple moisture sensor that can be used to detect soil moisture. When the soil is dehydrated, the analog value of the sensor output will decrease, and vice versa. Use this sensor to make an automatic watering device when you are long. Time is not at home or watering time, it can sense whether your plant is already thirsty. Prevent plants from withering to know that it is caused by lack of water. With the controller to make your plants more comfortable, the garden is smarter.

    The sensor surface is metallized to extend its life. Insert it into the soil and read it using an AD converter. With its help, the plant will remind you: I want to drink water, please give me Drink a little water.
