ERS Sound is a LoRaWAN™ room sensor that measures indoor environment. ERS sound is enclosed in a room sensor box and is designed to be wall mounted. Inside the ERS you will find five internal sensors: Temperature sensor, humidity sensor, light sensor, Sound level sensor (peak and average) and a motion sensor (PIR). ERS sound is powered by two 3,6V AA lithium battery(ER14505). The Battery life is estimated to be 3 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.
