The Dragino DS03A-LB LoRaWAN Door Sensor is a cutting-edge solution for monitoring door statuses within IoT frameworks. Seamlessly integrated with Telemetry2U, it provides real-time updates on door openings and closings, offering comprehensive insights into entry patterns and security breaches.

Long-Range, Low-Power Communication: Utilising LoRa wireless technology, the DS03A-LB ensures long-range data transmission while maintaining low power consumption. This technology guarantees reliable communication over vast distances, making it ideal for expansive premises. Combined with Telemetry2U's platform, it offers a streamlined and efficient way to monitor entry points remotely.

Intelligent Data Management: The device is programmed to send periodic updates every two hours and instantly reports each door activity. It efficiently tracks the number of door openings and the duration of each open state. Users have the flexibility to customise the data uplink settings, enabling the DS03A-LB to adapt to various monitoring needs when used with Telemetry2U's versatile platform.

Data Logging and Open Alarm Functionality: In areas with intermittent LoRaWAN coverage, the DS03A-LB's Datalog feature ensures no data is lost. It stores information when the network is unavailable and automatically uploads it once connectivity is restored. Additionally, the Open Alarm feature alerts users if a door remains open beyond a set threshold, enhancing security protocols within the Telemetry2U ecosystem.

Robust Design for Outdoor Applications: Designed for both indoor and outdoor use, this sensor boasts a weatherproof enclosure and operates effectively across a wide temperature range. Its industrial-grade battery ensures long-term, maintenance-free operation, aligning with Telemetry2U's commitment to durability and reliability in IoT solutions.
