Batteries not included
ERS lite is a LoRaWAN™ room sensor that measures the room climate. ERS lite is housed in a room sensor box and designed for wall mounting. Inside the ERS lite there are two sensors: a temperature sensor and a humidity sensor. The ERS lite is powered by a 3.6V AA lithium battery.
The battery life is estimated to be up to 10 years, but depends on sample interval, transmission interval, data rate and environmental factors. All Elsys sensors are equipped with NFC (Near Field Communication) for easy configuration with an Android phone. With the application "Sensor settings" you can change sampling rate, data rate, encryption codes, triggers, activation and much more.
