12V Raindrops Controller Module – Rain Sensor For Arduino, Foliar Moisture Detection

Working on a weather station or auto sprinklers?

This 12V raindrops controller module detects rain and foliar moisture—perfect for Arduino or other microcontroller projects.

It's a basic sensor: when water hits the board, it sends a signal.

Simple, effective, and cheap.

Brand new, unbranded, but it does the job.

No MPN or UPC, just a raw component for tinkerers.

Hook it up, code it, and make something cool.

Automatic plant watering?

Rain-sensing windows?

Go for it.

Small board, big potential.

If you're into electronics, grab a couple and experiment.

They're easy to use and surprisingly accurate.

Add it to your parts bin and see what you can build.
