The Mymesh add-on PIR is designed to be fitted into a luminaire casing providing a highly sensitive presence sensor that connects easily to the Micro BLC. It enables you to control a single or group of nodes (e.g. lighting fixtures or blinds) based on the presence of occupants.
Simply plug it in, commission the micro BLC with the preferred settings and start using the sensor to your liking. Push it through a cut out hole and lock in place with a transparent nut.
