The Dragino CPL03-LB LoRaWAN Contact Sensor is a pivotal tool in IoT applications, designed to meticulously monitor dry contact status, open times, and counts. Its integration with Telemetry2U elevates its capability, offering users real-time updates and insightful data on contact events.

Tailored Data Transmission: Programmed to send daily updates and report each contact action, this device ensures thorough monitoring. It boasts the flexibility to customise uplink settings for each event, allowing users to opt for periodic summaries instead of instant updates, which is particularly useful when integrated with the Telemetry2U platform for varied operational needs.

Long-Range, Low-Power Communication: Utilising advanced LoRa wireless technology, the CPL03-LB excels in sending data over long distances at low data-rates. This technology ensures ultra-long range communication with minimal power consumption, making it an ideal match for expansive areas when used in conjunction with Telemetry2U's system.

Enhanced Features for Reliable Monitoring: The sensor's Open Alarm feature provides instant notifications for specific contact events, while its Datalog capability ensures no data is lost even in the absence of a LoRaWAN network, automatically updating once the network is restored. These features, combined with Telemetry2U's analytics, offer a comprehensive monitoring solution.

Built for Endurance: With its weatherproof enclosure and industrial-grade battery, the CPL03-LB is built to withstand outdoor conditions and a wide range of temperatures, ensuring reliability and longevity. Its 8500mAh Li-SOCI2 battery promises up to 5 years of uninterrupted operation, aligning with Telemetry2U's promise of long-term, maintenance-free solutions.

User-Friendly Configuration: The device supports BLE for straightforward configuration and wireless OTA updates, enhancing user experience. Pre-loaded with unique LoRaWAN registration keys, it simplifies the setup process and automatically connects to the network on power-up, seamlessly integrating with Telemetry2U's user-friendly interface.
