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.
