DDS75-LB LoRaWAN Distance Sensor Node 868MHz

The DDS75-LB is a LoRaWAN distance sensor specifically designed for IoT solutions. Using ultrasonic technology, it measures the distance between the sensor and a flat object. Thanks to the internal temperature compensation, the measurement data is particularly reliable. The sensor is suitable for a wide range of applications, from liquid level measurement, water level measurement in rivers, snow quantities to parking space monitoring. This robust sensor node, packaged in a weatherproof housing, is ideal for outdoor use and is powered by an 8500mA Li/SOCl2 battery, ensuring a long operating time. The DDS75-LB not only serves as a simple sensor node, but is specifically designed to facilitate the rapid implementation of industrial LoRa and IoT applications. The wireless part of the node is based on the SX1262, which allows data transmission over very long distances at low data rates. This ensures an exceptionally wide range, high interference security and optimizes power consumption. Equipped with a powerful 48 MHz ARM microcontroller, 256KB Flash and 64KB RAM, the DDS75-LB is ready for all kinds of projects. The DDS75-LB has an integrated BLE module, which allows convenient configuration of the sensor from your mobile phone. It also supports OTA updates over a private LoRa protocol, significantly simplifying maintenance. This sensor node is the third generation of the popular LDDS75 from Dragino and offers a mature LoRaWAN stack as well as application software. You can use the pre-installed software for your IoT projects or flexibly adapt the software to different requirements.

Each sensor comes preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server and the sensor automatically establishes a connection when switched on, if network coverage is available.
