pdfOccupancy Sensors
APC Smartwave’s occupancy sensors can be used to measure room or desk occupancy for dynamic workplace management, facility management and workplace statistics.

Desk Sensors – ERS Desk
ERS Desk is a LoRaWAN™ sensor for measuring desk occupancy. ERS Desk is designed to mount under the desk and senses when somebody is using the desk (either standing or sitting). It can be used for dynamic workplace management, facility management and workplace statistics. The sensor also measures temperature humidity and light. All Elsys sensors are equipped with NFC (Near Field Communication) for easy configuration with an Android phone. All parameters can also be changed over the air from the server. All our sensors are built on the LoRaWAN™ stack from Semtech.

Room Sensors – ERS
ERS and ERS-lite are LoRaWAN™ room sensors for measuring indoor environment. ERS is enclosed in an room sensor box and it is designed to be wall mounted. All Elsys sensors are equipped with NFC (Near Field Communication) for easy configuration with an Android phone. With our application “Sensor Settings“, you can change sample rate, data rate, encryption keys, triggers, activation and more. All our sensors are built on the LoRaWAN™ stack from Semtech.
