Overview & Battery Information ▲
The ERS2 is a wireless LoRaWAN® sensor for indoor environments that measures temperature, humidity, light, and motion (PIR).
This article provides an overview of the Elsys ERS2 LoRa only, the ERS CO₂ LoRa sensor is not covered. As you're are deploying these in your smart office in combination with the GoBright solution, please ensure you have the GoBright AGW installed.
Important: Batteries are not included. The ERS2 requires 2 x AA 3.6V lithium batteries. Standard 1.5V batteries are not supported and will not power the device.
