Description

 

ERS Eye is an advanced room occupancy and indoor climate sensor for 
LoRaWAN® wireless network. The sensor measures temperature, humidity, light 
intensity, and detects occupancy. It can detect occupancy based on body heat, 
not only by movement. 

ERS Eye is a battery-powered device and is designed to 

be mounted on the ceiling. It is e

quipped with NFC (Near Field Communication) 

and can easily be configured from a smartphone.

  

 

 

The barcode contains DevEUI and sensor type. This label is located at the back 
of your device,
