Elsys LoRa LoRaWAN ERS Eye Room Sensor for Temperature

Monitor temperature, humidity, light, and occupancy with exceptional accuracy using the ELSYS ERSEYE, a LoRaWAN-enabled indoor climate sensor engineered for smart building and facility management. With a battery life of up to 10 years from two AA lithium cells, this sensor delivers long-term, maintenance-free operation.

Overview

The ERSEYE is a versatile sensor that combines four sensing functions in one compact device. It measures ambient temperature from 0 to 40 °C with ±0.5 °C accuracy, relative humidity from 0 to 85 %RH with ±2 %RH accuracy, and light intensity up to 65,535 lux. A built-in PIR sensor detects occupancy up to 5 meters away with a 90° horizontal and 60° vertical detection angle, making it ideal for presence-based automation.

What stands out

• LoRaWAN Class A connectivity with support for EU868, US915, AS923, AU915, KR920, and IN865 frequency bands.
• NFC and LoRaWAN downlink configuration for easy setup and remote parameter adjustment.
• Configurable transmission intervals from 1 to 1440 minutes to balance data granularity and battery life.
• IP20-rated ABS enclosure suitable for indoor wall mounting via screws or adhesive.
• Powered by two ER14505 lithium batteries, providing up to 10 years of operation under typical conditions.
