DS03A-LB LoRaWAN Door Sensor / Window Contact Node 868MHz

The DS03A-LB is an advanced LoRaWAN door sensor designed for use in a variety of environments. This device is ideal for applications where reliable and accurate monitoring of doors or windows is essential. This robust sensor node, packaged in a weatherproof enclosure, is ideal for outdoor use and is powered by an 8500mA Li/SOCl2 battery, ensuring long operation. The DS03A-LB is more than just a sensor node. It is designed to enable the rapid implementation of industrial LoRa and IoT solutions. The wireless part of the node is based on the SX1262, allowing data transmission over very long distances at low data rates. This ensures an exceptionally long range, high immunity to interference, and optimized power consumption. Equipped with a powerful 48 MHz ARM microcontroller, 256KB Flash, and 64KB RAM, the PS-LB-NA is prepared for all types of projects. The DS03A-LB has an integrated BLE module that allows convenient configuration of the sensor from your mobile phone. It also supports OTA updates via a private LoRa protocol, greatly simplifying maintenance. This sensor node is the third generation of the popular DS03A-LB 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. This sensor is excellent for use in residential buildings, offices, industrial plants, and other places where reliable monitoring of doors or windows is required. It can also be integrated into smart home systems to enhance safety and efficiency.

Each sensor is preloaded with a set of unique keys for LoRaWAN registrations. These keys are registered on the local LoRaWAN server, and the sensor automatically connects after being powered on if network coverage is available.
