Smart Door and Window Sensor with ZigBee Wireless Alarm and 22mm Sensing Distance
This smart door and window sensor is a practical addition to a connected home, offering monitoring for doors and windows. It uses a ZigBee wireless connection to link with a compatible smart home system, and it requires the Mi Home app, available from the Apple Store or Google Play, for setup and control. When a door is opened, the sensor triggers a light and ring, and the light can automatically turn on when the door is pushed. For times when you are away, the away-from-home mode rings the bell if someone breaks in, and it can prompt a connected IP camera (not included) to take video. The sensor also serves a ventilation purpose: when a window is opened to let fresh air into the room, the sensor detects this. The compact size makes installation straightforward. The maximum sensing distance is 22mm, and it operates in temperatures from -10 to 50 Deg.C and humidity from 0 to 95pct RH. A built-in CR1632 cell battery powers the unit. The package includes one alarm, and the colour option is listed as Picture colour.

No further material details are provided in the source text.
Size and Practical Fit
The maximum sensing distance is 22mm, which defines the gap or movement range it can detect. The compact size means it can be fitted to most standard doors and windows without taking up much space. No other dimensions are stated. The sensor is intended for indoor use where the temperature and humidity remain within the stated ranges. The colour option is listed as Picture colour.
Uses and Placement
This sensor is suited to both everyday home monitoring and more specific security scenarios. It can be placed on entry doors, windows, or other openings where you want to know when they are opened. It works with the Mi Home app and a ZigBee network.
Event or Professional Use
In away-from-home mode, the sensor rings the bell if a break-in is detected and can trigger a connected IP camera (not included) to record video. This makes it useful for monitoring a property while you are absent. It can also be used on windows to sense when they are opened for ventilation. The stated operating limits are -10 to 50 Deg.C and 0 to 95pct RH.
Everyday Home Use
For daily use, the sensor triggers a light and ring when a door is opened, and the light can turn on automatically when the door is pushed. It helps keep track of when windows are opened to let fresh air in. Installation is simple due to the compact size. The built-in CR1632 battery powers the device. The Mi Home app is needed for control and notifications.
Benefits and Buying Value
The sensor offers a straightforward way to add door and window monitoring to a smart home setup. It relies on a ZigBee connection and a replaceable battery, and it integrates with the Mi Home app. The stated sensing distance of 22mm and broad operating temperature and humidity ranges define its practical limits.
Reuse and Low Maintenance
The built-in CR1632 cell battery can be replaced when needed, which supports continued use. The sensor has no listed consumables beyond the battery. Its plastic housing can be wiped clean if required. There are no specific care instructions in the source text, so only basic surface cleaning is advisable. The operating ranges are -10 to 50 Deg.C and 0 to 95pct RH.
