ERS Eye is a sensor for measuring occupancy and the indoor environment. It is enclosed in a room sensor box and is designed to be mounted in the ceiling. ERS Eye is completely wireless and powered by two 3.6V AA lithium batteries. Inside you will find internal sensors for measuring room occupancy (PIR and infrared), temperature, humidity, and light.

This is an indoor LoRaWAN® room sensor for measuring indoor environment and occupancy. It has a clean design and is ideal for mounting in the ceiling above areas where occupancy needs to be measured.  Not only will you have the possibility to optimize the usage of meeting rooms, offices, or other public areas, you will also have full control over the environment there.
