It detects and reports open and close events in real time, while also recording open duration and cumulative open counts — giving users complete visibility into door activity through any compatible IoT server. The General (GE) version ships without a SIM card, making it ideal for deployments where a specific carrier or local SIM is required.\u003c\/p\u003e\n\n\u003cp\u003eBuilt for outdoor and demanding environments, the DS03A-NB-GE features a weatherproof enclosure, a 40cm probe, and an 8500mAh Li-SOCl2 battery capable of lasting several years under normal usage. It supports multiple uplink protocols including MQTT, MQTTs, UDP, and TCP, and can be configured remotely via Bluetooth 5.1 or updated over-the-air. A built-in datalog function ensures no data is lost during network outages, automatically syncing once connectivity is restored.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cbutton
