Introduction to Rain Sensor Product

Rain Sensor for detecting rain or water

Are you looking for a rain sensor that is rugged and easy to interface to your controller or computing system? Check out this sensor that we are going to introduce to you here. It is simple to connect and is simple to install.

This rain sensor uses IR optical technology to detect the presence of rain water. Compare to resistive rain sensor or capacitive rain sensor, it does not have dedicated sensitive components which need to be exposed to the rain water. It is operated entirely on electronic and IR optical light without any moving mechanism. Using IR optics to sense rainwater makes it more robust and longer lasting compare to other types of rain sensor.

The rain sensor is self-contain in a waterproof casing and does not contain moving mechanical parts. This makes it a rugged and an intuitive rain sensor to maintain.
