Soil Moisture Sensor Capacitive Module Hygrometer V1.2 Compatible with Arduino and Raspberry Pi including an E-Book

"With this capacitive soil moisture sensor/hygrometer, you can easily measure plant moisture and detect when the plant needs watering.Our soil moisture sensor has a built-in amplifier that allows it to be connected directly to an analog input of a microcontroller.The measuring probe is inserted into the soil and measures the soil's capacitance, which varies with moisture.Compared to its predecessor, our capacitive soil moisture sensor, or capacitive soil moisture sensor, exhibits no wear or corrosion.This product includes an e-book that provides helpful information on how to get started with your project. It enables quick installation and saves time on the setup process. It includes a series of application examples, comprehensive installation guides, and libraries."
