Multisensore ELSYS ERS EYE Temperatura umidità luce movimento presenza

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.

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.
