Solar-Powered NB-IoT / LTE-M Ultrasonic Distance Sensor

The Solar-Powered NB-IoT / LTE-M Ultrasonic Distance Detection Sensor is a long-life, maintenance-free solution for remote level and distance measurement. Equipped with an industrial ultrasonic probe and an integrated 0.9W solar panel + Li-ion rechargeable battery, it delivers continuous operation in outdoor environments without needing battery replacements.

Using NB-IoT / LTE-M cellular connectivity, the sensor sends precise distance readings—ranging from 280 mm to 7.5 meters—directly to your IoT platform using MQTT, MQTTs, TCP, UDP, or CoAP. Built-in temperature compensation ensures stability and accuracy across varying weather conditions.

Designed for harsh Australian conditions, the sensor’s IP66 enclosure protects against dust, rain, and UV exposure, making it ideal for agricultural tanks, dams, silos, waste bins, parking bays, stormwater pits, and industrial infrastructure.

Configuration is simple via Bluetooth (BLE), and remote changes can be made using downlink commands or AT instructions. OTA firmware updates ensure long-term support and adaptability.

Works with ProSight and all third-party IoT software.
