D23-LS LoRaWAN 3-Channel Temperature Sensor Node 868Mhz with Solar

The D23-LS from Dragino is an 868Mhz waterproof LoRaWAN sensor node with three temperature sensors and solar power supply. The DS18B20 temperature sensors used to measure within a range of -55°C to 125°C with a tolerance of ±0.5°C (max ±2.0°C). The module is connected to a 1.5m sensor cable, which terminates into three separate temperature probes. This robust sensor node, packed in a weatherproof housing, is ideal for outdoor use and is powered by solar energy and an integrated battery, ensuring a long operational duration. The D23-LS is more than just a sensor node. It has been designed to enable rapid implementation of industrial LoRa and IoT solutions. The wireless part of the node is built on the SX1262 which enables the transmission of data over very long distances at low data rates. This ensures exceptionally far range, high immunities to interference, optimizing power consumption. Powered by a powerful 48 MHz ARM microcontroller, 256kB Flash and 64kB RAM, the D23-LS is prepared for all kinds of projects. The D23-LS has an integrated BLE module, allowing easy configuration of the sensor from your mobile phone. It also supports OTA updates via a private LoRa protocol, significantly simplifying maintenance. This sensor node is the third generation of the popular LSN50V2-D23 from Dragino and offers a mature LoRaWAN stack and application software. You can use the pre-installed software for your IoT projects or adjust the software flexibly to different requirements.

Each sensor is preloaded with a set of unique keys for LoRaWAN registration. These keys are registered with the local LoRaWAN server and the sensor will automatically connect on power-up where network coverage is available.
