rain sensor

Droplet-sensing device

A rain sensor is a device that detects water or moisture, typically used to trigger automatic responses.

Windshield wipers with rain sensors activate when droplets hit the glass.

Irrigation systems use rain sensors to skip watering cycles during wet weather.

The sprinklers didn't run last night—the rain sensor detected the storm.
