Dragino-LoRaWAN Distance Detection Sensor
The Dragino LDDS45-LB is a long-range LoRaWAN® distance detection sensor designed to measure the distance between the device and a target surface using ultrasonic sensing technology. Integrated with Microclimates EnvOS®, the sensor provides real-time distance measurement, level monitoring, alerts, and historical reporting for applications such as tank level monitoring, smart waste systems, parking management, and environmental infrastructure. With ultra-low power consumption and industrial battery life, it is built for long-term, maintenance-free remote deployment.
