This is a simple soil humidity sensor aims to detect the soil humidity. If the soil is lacking in water, the analog value output by the sensor will decrease, otherwise, it will increase. If you use this sensor to make a automatic watering device, it can detect whether your botany is thirsty to prevent it from withering when you go out. Using the sensor for Arduino controller makes your plant more comfortable and your garden smarter.

The soil humidity sensor module is not as complicated as you might think, and if you need to detect the soil in your project , it will be your best choice.The sensor is set with two probes inserted into the soil, then with the current go through the soil, the sensor will get resistance value by reading the current changes between the two probes and convert such resistance value into moisture content. The higher moisture (less resistance), the higher conductivity the soil has.  

Features:
The surface of the sensor have undergone metallization process to prolong its service life.
Insert it into the soil and then use the AD converter to read it.
Great for small proof of concept projects
With the help of this sensor, the plant can remind you: I want to drink, please give me a drink of water. 
Excellent board and great quality!
