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.

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)....
For microphones and many other applications. This module is simply switched between a power amplifier and a weak signal source.
Switches on other devices with the built-in relay contact after pushing the button and automatically switches them off again after a set time. The time can be stopped any point by pressing the second button. Two push buttons are required for use.
