Elsys ELT Lite with an external antenna (sold separately) is an outdoor LoRaWAN sensor for measuring in outdoor environments. It is enclosed in an IP67 box which makes it ideal for mounting in advanced places or in extreme conditions. The ELT Lite has one generic output and can be combined with an electricity meter, flow meter, analog sensor or a moisture sensor. 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).
