Smart Door and Window Sensor with ZigBee and 22mm Sensing Distance

This smart door and window sensor offers a straightforward way to keep an eye on entry points at home. It uses a ZigBee wireless connection to link with a compatible smart home system, and it can trigger a light and ring alert when a door is opened. The light can also switch on automatically when the door is pushed. For times when you are away, the sensor can sound a bell on intrusion and work alongside an IP camera (not included) to record video. It also has a role in everyday ventilation, letting you know when a window is opened to bring fresh air into a room. The compact unit is easy to install and runs on a built-in CR1632 cell battery. Setup is handled through the Mi Home app, available from the Apple Store or Google Play.

Features and Construction

The sensor is designed for simple placement on doors and windows, with a small body that fits into everyday spaces. Its main functions focus on entry alerts and integration with a broader smart home setup, using ZigBee for wireless communication.

Material and Build

The sensor is powered by a built-in 1pc CR1632 cell battery, which supports wireless operation. The compact construction makes it suitable for mounting on doors and windows without taking up much room. It communicates over a ZigBee wireless connection, so no hardwiring is required between the sensor and the rest of the system. The working temperature range is -10 to 50°C and the working humidity range is 0 to 95% RH, covering typical indoor conditions.

Size and Practical Fit

The maximum sensing distance is 22mm, which refers to the gap between the sensor and its magnet. This measurement matters when positioning the two parts on a door or window frame. Because the unit is small, it can be installed in tight spaces. The built-in battery means there is no external power cable to route, keeping the installation neat. The sensor is intended for indoor use within the stated temperature and humidity limits.

Uses and Placement

This sensor suits both everyday home monitoring and more specific security routines. It can be placed on main doors, back doors, or windows where you want to know when they are opened.

Event or Professional Use

When you are away from home, the sensor can trigger a bell alert if someone breaks in. It can also work with an IP camera, which is not included, so that video can be captured during an alert. This makes it useful for keeping an eye on a property while you are out. The ZigBee connection allows it to be part of a wider smart home setup, and the Mi Home app is used for control.

Everyday Home Use

At home, the sensor can light and ring when a door is opened, giving a clear signal that an entry point has been used. The light can turn on automatically when the door is pushed, which can be helpful in low-light hallways or entrances. It also supports ventilation habits: when a window is opened to let fresh air in, the sensor can detect that action. The small size means it can be fitted to most standard doors and windows without drawing attention.

Benefits and Buying Value

The sensor focuses on practical alerting and easy integration rather than complex installation. It provides a simple way to add door and window monitoring to a ZigBee-compatible smart home.

Reuse and Low Maintenance

The built-in CR1632 cell battery powers the sensor, so there is no need for a wired connection. The unit is designed for ongoing use within the stated temperature and humidity ranges. Because it is compact and installs easily, it can be moved or repositioned if needed. The Mi Home app allows you to manage the sensor as part of your smart home setup.
