Grove - Water/Rain Sensor

This sensor works by having a series of exposed traces connected to ground and interlaced between the grounded traces are the sens traces. The sensor traces have a weak pull-up resistor of 1 MΩ. The resistor will pull the sensor trace value high until a drop of water shorts the sensor trace to the grounded trace.

For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting Started and Introduction to Grove before your use of the product.

Believe it or not, this circuit will work with the digital I/O pins of your Arduino or you can use it with the analogue pins to detect the amount of water induced contact between the grounded and sensor traces. Suitable to detect rainfall, tank overflow, water leakage.

You can get grove HAT for Raspberry Pi or if you want to use this module with Arduino board, you can get grove shield for Arduino. Also great for the Maker Pico board with grove adapters
