Details Additional Info Data Sheet
The LoRaWAN® EMS2 Desk Occupancy Sensor from Elsys measures both the indoor environment and desk availability. It's completely wireless, battery-operated compact design is ideal for indoor use to give you a full overview of occupancy and conditions in workplace facilities, ideal for open-plan offices and hot-desking environments. Save both money and office space by installing Elsys ERS Desk sensors. Easily retrofitted and unobtrusive, they are ideal for mounting under desks or tables, making it possible to better utilise seating areas and other office spaces. Since people are often standing or sitting still while using a desk or break room table, the ERS Desk is equipped with a thermopile to detect presence based on body heat in addition to motion.
Ideal for a wide range of applications, this desk occupancy sensor is used in:
