ELT Ultrasonic is a LoRaWAN sensor with an external antenna (sold separately) 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 Ultrasonic can measure analog or digital signals from an external sensor and has internal sensors for measuring distance, temperature, humidity, acceleration, and atmospheric pressure. It can measure the water level under a bridge, trash level in a container, and much more. It can easily be configured with a mobile app and the expected battery life is up to 10 years (depending on transmit interval, data rate and usage environment).
