Zigbee smart door sensor typically operate based on the reed switch principle. A reed switch is a device made of soft magnetic material that contains two contacts inside. When there is no magnetic field, these two contacts are separated; When magnetized by a magnetic field, the two contacts will come into contact, thereby connecting the circuit. In practical applications, magnets are usually fixed on doors, while reed switch components are fixed on door frames close to the magnets. When the door is closed, the magnet approaches the reed switch and the circuit is connected; When the door is opened, the magnet moves away from the reed switch and the circuit is disconnected. Through this method, Zigbee smart door sensors can monitor the real-time opening and closing status of the door.
Due to the use of soft magnetic materials in door and window sensors, if they are in a strong magnetic field environment, they may be mistakenly classified as closed. Therefore, it is advisable to avoid placing the sensor near strong magnetic fields during installation.
If sensors are installed on iron doors and windows, attention should be paid to the attenuation effect of wireless signals, which may cause unreliable communication with the gateway. It is recommended to avoid installing on iron safety doors and use non-metallic doors and windows as much as possible.
The internal contacts of the reed switch are not fixed and can move. Strong vibrations may lead to misjudgment. Therefore, it is recommended to install the reed switch in areas with less vibration, such as door and window frames.
Each model of door and window sensor has an effective distance limit. During installation, it is important to ensure that the distance between the sensor and the magnet is within an effective range, otherwise it may result in the inability to detect the closed state
