The Dragino DS03A-LB/LS is a LoRaWAN door/window open-close status sensor designed for industrial facilities, data centers, warehouses, and smart building automation projects. Its built-in magnetic contact sensor detects the real-time status of doors, windows, or covers and securely transmits data to your server via the LoRaWAN network. The device sends data periodically (every 2 hours) and delivers instant alerts for each open/close event. IoTMarketi, a multi-brand IoT product catalog in Turkey, provides technical details for this device; we recommend requesting a project quote for procurement and integration.

FAQ

Q: What is the difference between DS03A-LB and DS03A-LS? A: DS03A-LB uses an 8500 mAh Li-SOCl2 battery for 5-year operation. DS03A-LS combines a solar panel with a 3000 mAh Li-ion battery, offering extended runtime in continuously sunlit environments.

Q: Is the device compatible with LoRaWAN networks in Turkey? A: Yes. The DS03A-LB/LS supports the EU868 frequency band and is compatible with Turkey's LoRaWAN infrastructure (e.g., The Things Network, Kerlink).

Q: Will data be lost if the network connection drops? A: No. The Datalog feature stores data locally during network outages and transmits it without loss once the connection is restored.

Q: How do I configure the device? A: You can configure it wirelessly via BLE v5.1 using a mobile app—no need to open the device.
