The Dragino LDS02 door sensor detects the door open or closed status and sends it via LoRaWAN. The LDS02 sends periodically every day and every time the door is opened or closed.
The batteries are not included in the scope of delivery.

The LDSO2 LoRaWAN Door Sensor is designed for applications such as Smart Buildings & Home Automation, Logistics & Supply Chain, Smart Metering, Smart Agriculture, Smart Cities, and Smart Factories. It is particularly useful for door open/close detection and sending open alarms.
The sensor uses LoRaWAN Class A v1.0.3 to uplink data to an IoT server. It transmits data periodically and also whenever the door's open or close status changes.
The sensor is powered by two AAA LR03 batteries. A fresh set of batteries can support approximately 16,000 to 70,000 uplink packets.
The sensor can be configured using AT commands via a USB to TTL adapter or remotely via LoRa downlink commands.
The uplink payload consists of 10 bytes containing information such as the door status, battery level, MOD, total open events, last door open duration, and alarm bit.
The sensor supports downlink commands such as TDC, RESET, Confirmed mode, Clear Counting, Alarm Enable/Disable, ADR/DR, and Alarm Timeout.
During power on, the GREEN, RED, and BLUE LEDs will light for 1 second each. A successful join is indicated by a GREEN LED for 5 seconds. A GREEN LED blink indicates an uplink message, and a BLUE LED blink indicates a downlink message.
The sensor can send an alarm if the door remains open for a configurable timeout period. This feature can be enabled or disabled via downlink command.
