Our NB-IoT smart door sensor is a security alarm device based on NB-IoT (Narrowly defined Internet of Things) communication technology. After the smart door sensor captures the information of the door opening or closing, it is transmitted to the server and user’s phone through NB-IoT. NB-IoT door sensors do not need to be directly connected to nearby base stations through gateways, making setup simpler. We support customized services, which can customize the size, color and appearance of sensors, and can customize NB-IoT smart door sensors according to user needs.
Real time monitoring and alarm: Real time detection of door opening or closing information and real-time transmission to users.
Convenient connectivity: It eliminates the dependence on smart gateways or WiFi, making it more convenient to use.
Anti disassembly alarm:The sensor has anti disassembly function, and once it is illegally disassembled, it will immediately trigger an alarm.
Historical record query: The cloud platform supports historical record query, and users can view the switch records of doors and windows for easy traceability and analysis

The working principle of NB-IoT smart door and window sensors mainly relies on the attraction and separation of magnets and reed switches. When the doors and windows are closed, the circuit is connected. When the doors and windows are opened, the circuit is disconnected. This on-off change is captured by sensors and converted into electrical signals, which are transmitted to the cloud or users’ mobile devices through NB-IoT technology, thereby achieving real-time monitoring of the status of doors and windows.
When installing NB-IoT smart door sensors, it is important to ensure that the distance between the magnet and the reed switch is appropriate to ensure accurate circuit continuity.
The sensor should be installed in a location that is not easily obstructed or damaged to ensure its normal operation.
Users should regularly check the battery level and signal quality of the sensor to ensure that it is always in good working condition.
During use, users should protect the anti disassembly device of the sensor to prevent it from being illegally disassembled.
