ZigBee-enabled smart door and window sensor Extralink Smart Life Door and Window Sensor is a smart door and window sensor that detects the opening and closing of doors or windows. The sensor connects to the Extralink multi-function gateway via the ZigBee protocol after adding it in the Tuya application and allows you to create smart home scenes. The sensor has low power consumption and long battery life. The sensor also has anti-tampering and low voltage reminder function. Key Features of the Extralink Door and Window Sensor Detects the opening and closing of doors or windows Connects to the Extralink Multi-Function Gateway via the ZigBee protocol Has low power consumption and long battery life Has anti-tampering and low voltage reminder functions It is easy to install and use with the Tuya app Detects the opening and closing of doors and windows The Extralink Door and Window Open Sensor detects the change in the distance between the main and auxiliary modules that are placed on doors or windows. When the door or window is opened or closed, the sensor sends a signal to the Extralink Smart Home Gateway, which can trigger other smart devices. For example: You can set the house bell to automatically turn on when the sensor detects a door opening Set the sound and light alarm to automatically activate when the sensor detects a window is open The camera will automatically turn on and start recording when the sensor detects an opening Connect to the Extralink Multi-function Gateway using ZigBee Extralink Door and Window Sensor connects to the Extralink Smart Life Multi-function Gateway using the ZigBee protocol via the Tuya app , which is safe, reliable and compatible with other smart devices. ZigBee is a low-power wireless communication protocol that enables the creation of mesh networks. A mesh network is a network in which each device can communicate with other devices directly or through intermediate nodes. This makes the mesh network resistant to interference and ensures full signal coverage everywhere. Low power consumption and long battery life The Extralink door and window sensor has low power consumption and long battery life. The sensor is powered by two CR1632 batteries with a capacity of 140 mAh each. The sensor has a sleep mode that reduces power consumption to a minimum. The sensor can work for up to 2 years with normal use (30 times a day). The sensor also has a low voltage reminder function that notifies the user when the battery needs to be replaced. Anti-tampering feature and easy installation The Extralink sensor has an anti-tampering feature that prevents unauthorized removal or damage to the sensor. When someone tries to remove or tear the sensor, the sensor will send an alarm signal to the Extralink multi-function gateway, which can trigger other smart devices.
