https://www.aiotkart.com/web/image/product.template/17655/image_1920?unique=9944ae1

The Dragino DDS75-LB LoRaWAN® Ultrasonic Distance Detection Sensor is a long-range industrial IoT sensor designed for high-accuracy distance and level measurement applications. As an Authorized Dragino Distributor in India, AIoTkart® supplies the DDS75-LB for smart infrastructure, industrial automation, parking systems, sewer monitoring, and large tank level measurement projects.

The DDS75-LB uses advanced ultrasonic sensing technology with internal temperature compensation to ensure reliable and stable readings across harsh environmental conditions. It measures the distance between the sensor and a flat object and transmits the data wirelessly to a LoRaWAN® IoT server for remote monitoring. With its extended measurement range of up to 7.5 meters and ultra-low power consumption, the DDS75-LB is ideal for large tanks, wide-area monitoring, and outdoor deployments.
