Description of LoRaWAN Door Sensor

HKT LoRaWAN Door sensor is a door sensor that can detect the open/closed state of a door and uplink to the LoRaWAN network. With good LoRaWAN network coverage, Lora door sensor can transmit tens of thousands of upstream packets. With poor network coverage, LoRaWAN can transmit over 1,000 upstream packets. Users can easily replace the battery for reuse.

The Lora door sensor will send data and the opening/closing action of each door at regular intervals every day. It also counts the number of doors opened and calculates the last time the door was opened.

Each Lora door sensor is pre-loaded with a unique set of keys for LoRaWAN registration, registering these keys to the local LoRaWAN server, which will connect automatically upon power-on.

Applications of Lora Door Sensor

1. Wireless Alarm and Security Systems 2. Home and Building Automation 3. Industrial Monitoring and Control

4. Smart Cities

5. Smart Factory
