ERS and ERS-lite are LoRaWAN™  room sensors for measuring indoor environment. ERS is enclosed in an room sensor box and it is designed to be wall mounted. Inside the ERS you will find five internal sensors: temperature sensor, humidity sensor, light sensor, and a motion sensor (PIR). For ERS-CO2 there is an additional CO2 sensor, and for the ERS-sound there is an additional sound sensor for peak and average dBa level. ERS is powered by two 3,6V AA lithium battery (one for ERS-lite). The Battery life is estimated to be up to 10 years but depends on sample interval, transmit interval, data rate and environmental factors. You are welcome to use our online battery lifetime calculator. All Elsys sensors are equipped with NFC (Near Field Communication) for easy configuration with an Android phone. With our application “Sensor Settings“, you can change sample rate, data rate, encryption keys, triggers, activation and much more.  All our sensors are built on the LoRaWAN™ stack from Semtech.
