LDS03A
Outdoor LoRaWAN Open/Close Door Sensor
The Dragino LDS03A is an Open/Close LoRaWAN Door Sensor. It detects door open/close status and uplinks to IoT server via LoRaWAN network. user can see the door status, open duration, open counts in the IoT Server. LDS03A is powered by a 8500mAh Li-SOCI2 battery. It can be used for up to 10 years. The LDS03A will send periodically data every 2 hours as well as for each door open/close action. It also counts the door open times and calculates the last door open duration. Users can also disable the uplink for each open/close event, instead, LDS03A can count each open event and uplink periodically.

Application guide
Choose the airflow range by deployment scenario

Cold Storage & Display Cases
For supermarket chillers, refrigerated display cases, cold storage deadzone detection, VAV terminals, and clean rooms.

HVAC Ducts & AHU Verification
For HVAC supply or extract ducts, filter pressure-drop monitoring, and air handling unit performance checks.

Industrial Ventilation & Fan Outlets
For main duct airflow, fan outlets, compressed air systems, and industrial ventilation monitoring.
How it works
Remote airflow monitoring via LoRaWAN
Deploy AirFlow-LN at critical airflow points, transmit measurements through a LoRaWAN gateway, and use platform data to detect weak airflow, filter problems, or abnormal ventilation conditions earlier.
- AirFlow-LN measures airflow in ducts, refrigeration, or ventilation points.
- LoRaWAN gateway receives data from distributed sensors across the site.
- Cloud platform visualizes trends and helps trigger maintenance decisions.
