## Summary description

The ELSYS ERS EYE is a wireless multi-sensor that measures temperature, humidity, light, motion, and occupancy based on body heat. It uses LoRaWAN technology for connectivity and is powered by AA lithium batteries. With dimensions of 76mm x 76mm x 23mm, it is compact and suitable for smart home applications. Ideal for monitoring indoor environments.

## Long description

ERS2 Eye is a wireless LoRaWAN sensor for indoor environments that measures room occupancy, temperature, humidity, light level and motion (PIR). The device has a compact Scandinavian design and is intended for use in offices, public spaces and homes. It runs on two AA 3.6V lithium batteries and offers long battery life; batteries are not included.
Advantages
The sensor detects presence using an IR occupancy sensor that can register people even when they remain still. It transmits measured values over LoRaWAN and supports remote configuration of sampling rate, data rate, encryption keys, triggers and activation via NFC with a smartphone or via downlink. The unit is low-maintenance thanks to long battery life and easily replaceable batteries.
Suitable for
 Monitoring room occupancy in meeting rooms and offices
 Indoor environmental monitoring for temperature and humidity
 Light level monitoring for lighting control or energy management
 Motion detection for basic presence-based automation
Key specifications
 Wireless technology: LoRaWAN
 Measured parameters: occupancy (IR), motion (PIR), temperature, relative humidity, light level
 Power: 2 × AA 3.6V lithium batteries (not included)
 Typical battery life: up to 10 years (depending on configuration and usage)
 Dimensions: 76 × 76 × 23 mm
 Configuration interfaces: NFC (smartphone), LoRaWAN downlink
How to use
Mount the sensor on a wall or flat surface at a suitable height for occupancy detection. Install two AA 3.6V lithium batteries, power on the device and register it in your LoRaWAN network. Configure sampling intervals, triggers and encryption keys either by holding an NFC-enabled smartphone near the device or by sending downlink configuration commands from your network server. Place the sensor where it has an unobstructed view of the monitored area for accurate occupancy and motion detection.
Usage recommendations
For reliable occupancy detection, position the sensor so its IR detector faces the area where people are most likely to be. Avoid pointing the device directly at heat sources or in direct sunlight. Choose sampling rates and transmission intervals that balance timely data with battery life according to your monitoring needs.
