Product Description
Technical Details
Dragino DDS45-LB – Energy-Efficient LoRaWAN Distance Sensor with Ultrasonic Technology and Temperature Compensation
The Dragino DDS45-LB is a versatile ultrasonic distance sensor for IoT applications. It transmits precise distance measurements between the sensor and a flat surface over the LoRaWAN network. The device features internal temperature compensation to maintain accuracy under changing environmental conditions.
Typical Use Cases:
Horizontal distance measurement
Liquid level monitoring in tanks
Smart trash bin and parking space analysis
Obstacle detection in robotics
Groundwater and sewage level monitoring
Automated control systems
For ease of configuration, the DDS45-LB supports Bluetooth Low Energy (BLE) and over-the-air (OTA) firmware updates. LoRaWAN ensures long-range, low-power communication with high interference immunity.
Powered by a long-lasting 8500 mAh Li-SOCI2 battery, the DDS45-LB is designed for deployments lasting several years.
Each device is preloaded with unique LoRaWAN registration keys and connects automatically once registered.
