Hygrometer Sensor Library for Arduino (Rain Drop and Soil Moisture)

What is it

This library (with examples) is designed to be integrated in projects using any kind of Hygrometer sensors like rain drop or soil moisture sensors (analog or/and digital). It retrieves analog/digital value from the sensor and gives the humidity status.

How to install

1. Download latest release

2. On your Arduino IDE, click "Sketch" menu and then "Include Library > Add .ZIP Libraries"

3. You can now use the library for your project or launch an example ("File > Examples")

How to connect Rain drop sensor or soil moisture sensor to your Arduino

Most hygrometer sensors have an analog and/or a digital output.

All rain drop sensors behave the same way:

Raindrop Sensor	Arduino
VCC	5V
GND	GND
A0	A1 (or any other analog pin)
D0	D2 (or any other digital pin)
