DS03A-LB/LS – LoRaWAN Outdoor Open/Close Door Sensor

The Dragino DS03A-LB/LS is an advanced LoRaWAN door sensor designed for outdoor Internet of Things (IoT) applications. It detects door open/close status and transmits the data to an IoT server via a LoRaWAN network. Users can monitor door status, opening duration, and the number of open events remotely through the cloud platform.

Leveraging the long-range, low-power capabilities of LoRa wireless technology, the DS03A-LB/LS ensures reliable data transmission over extended distances with minimal energy consumption. Its robust construction, wide temperature tolerance, and long-term power supply options make it ideal for industrial and outdoor deployments.

Key Features

• door open/close detection with real-time reporting
• dual reporting mode: periodic data transmission (default every 2 hours) and event-based uplink on door activity
• open alarm function: triggers an alert if the door remains open for a user-defined duration
• data logging (Datalog): stores data when the LoRaWAN network is unavailable; uploads automatically once the connection is restored
• wireless configuration and updates: supports Bluetooth v5.1 and LoRaWAN-based remote configuration, plus OTA firmware updates
• outdoor-ready design: IP-rated weatherproof enclosure, wide operating temperature range, and wall-mount support
• long-term power supply:
  • DS03A-LB: powered by an 8500 mAh Li-SOCI₂ battery (non-rechargeable) – up to 5 years of operation
  • DS03A-LS: equipped with a solar panel and a 3000 mAh Li-ion rechargeable battery for maintenance-free operation in sunlight-exposed locations
• pre-configured for LoRaWAN: each unit includes a unique set of activation keys for immediate auto-connect upon power-up
