Hygrometer Detection Soil Moisture Sensor Sensing Module

Hygrometer Detection Soil Moisture Sensor Sensing Module Soil Humidity Sensor Module for Arduino Automatic Watering System

This is a simple moisture sensor that 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, the garden is more intelligent.

The sensor surface is metalized to extend its use of time. Insert it into the soil and then use the AD converter to read it. With its help, the plant will remind you: I want to drink water, please give me a little water to drink.
