Rain Detector Module for Arduino
Varied resistance based on moisture on board

This listing is for a small moisture detection board.  The resistance of the two on board leads varies depending on how much moisture is touching it.  If you watch the above video, you get a full demonstration of how it works.  The board is essentially a variable resistor.  If a ton of moisture is touching the board, you can get resistances of down to 100k ohms or less.  If there is no moisture, or water touching the sensor board, the resistance will be more than 2M ohms.  It is easily interfaced with a comparator IC, such as the LM324.  This listing includes one sensor board. the specifications are below.  There is a rust prevention coating on the board to help it to keep from rusting/corroding.  If after reading this and after watching the above video you have any questions, please do not hesitate to ask =)  


Specifications:
Main Board Length: 53mm
Main Board Width: 40mm
Main Board Height: 77mm (With leads)
