User & Safety Instructions 190351 Kemo M152 Rain sensor Component 12 V DC
Description
Kemo's M152 module combines a liquid sensing plate and 12V normally open contact relay to produce a switching operation based on an input of rainfall or snowfall. The relay is activated when rain is detected on the sensor plate and de-activated when water is no longer present. Integrated heating avoids standing water on the plate once it has stopped raining.
Potential projects could include motorised windows, automated awnings or even automatic washing line covers! To use this module with 240V appliances, a secondary relay is required, activated on basis of the module's 12V signal. Choosing this relay depends on your application.
Features
Integrated 12V 2A SPST-NO relay
Sensor heating: Automatic activation, when it comes in contact with rain
LED 1: Operational display
LED 2: Relay message.
Hints
Before the rain water flows on to the rain sensor, it would be helpful if the rain water first flows through the roof or the gutter, because the dirt particles make the rain water (like distilled water) only conductive and thus ensure a reliable operation of the sensor.
