LDS02
LoRaWAN Door Sensor
The Dragino LDS02 is a LoRaWAN Door Sensor designed to detect door open/close status and send data to a LoRaWAN Network Server. Users can view the door status, open time, and open counts in an IoT platform by integrating it with the LoRaWAN Network Server. The sensor is powered by two AAA batteries, making it suitable for long-term use. These batteries can provide approximately 16,000 to 70,000 uplink packets. When the batteries run out, users can easily open the enclosure and replace them with standard AAA batteries. The device sends data periodically every day and for each door open/close action. It also counts the number of door openings and calculates the duration of the last door opening. Users can disable the uplink for each open/close event if preferred. In this mode, the device will count each event and upload the data periodically instead.

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.
