LoRaWAN distance sensor Dragino DDS45-LB

The DDS45-LB is the solution LoRaWAN for distance sensing for the Internet of Things. It is used to measure the distance between the sensor and a flat object. The distance sensor is a module that uses ultrasonic distance measurement technology, and temperature compensation performed internally to improve data reliability.

The DDS45-LB can be applied to scenarios such as horizontal distance measurement, liquid level measurement, parking control system, object proximity and presence detection, intelligent garbage can control system, robot obstacle avoidance, automatic control, sanitation, groundwater level monitoring, etc.

It determines the distance between the measurement object and the sensor and uploads the values ​​over a wireless connection to the LoRaWAN IoT server.

The LoRa wireless technology used in the DDS45-LB allows the device to transmit data and reach extremely long distances at low data rates. It provides ultra-long range spread-spectrum communication and high immunity to interference while minimizing current consumption.

DDS45-LB supports BLE configuration and wireless OTA update , which makes it easy for the user to use.

DDS45-LB is powered by Li-SOCI2 battery with a capacity of 8500 mAh , designed for long-term use up to 5 years.

Each DDS45-LB comes pre-loaded with a set of unique LoRaWAN registration keys, register these keys to your local LoRaWAN server and it will connect automatically after power on.
