Elsys EMS Door is a LoRaWAN opening activity sensor which tells when an object has been opened or moved. The compact design makes it perfect for mounting on door frames, window panes, cabinets or any other limited surface area. All Elsys sensors are equipped with NFC (Near Field Communication) for easy configuration with a smart phone. All settings, such as data rate, encryption keys, triggers and activation can be changed and managed in the Elsys configuration app “Sensor settings”. The battery life is estimated to be up to 10 years, depending on sample interval, transmit interval, data rate, and environmental factors. The sensor is powered by one 3,6V AA lithium battery (sold separately).
