EasySens® Light/Motion


The SR-MDS is a radio multi-sensor to measure light levels and detect motion. The SR-MDS is typically ceiling-mounted and powered by 24 V so as to permit reliable operations in rooms with low light levels (e.g. basements).

Application/type Ceiling sensor, Room sensor
Purpose Measure values
Measured values temperature, luminosity, motion
Interface EnOcean (868 MHz), EnOcean (902 MHz)
Configuration jumper
