Kemo Kemo M152K Rain sensor Assembled 12 V DC

When the fully insulated sensor plate gets wet (e.g. raindrops), a relay switches on. Unlike rain detectors with a metal sensor, this sensor works capacitive. In other words, it switches even when touched with distiled water (in completely clean rain). This allows roof windows Closed, awnings retracted or only rain reported. 2 built-in LEDs indicate the function. The sensitivity can be set. This text is machine translated.
