Mi Door and Window Sensor 2 (MCCGQ02HL) – Smart Home Security Sensor with Automatic Control, Works with Mi Home App

The Mi Door and Window Sensor 2 is a highly intelligent and compact smart home security device designed to enhance your home’s safety and convenience. Built by Xiaomi, a global leader in smart home technology, this sensor blends innovation, reliability, and user-friendly design in the perfect way. Whether you live in a small apartment or a large home, the Mi Door and Window Sensor 2 offers a seamless way to monitor entry points and automate your environment for greater comfort and peace of mind.

This upgraded version features a combination of a magnetic open/close detection system and an integrated light sensor, making it far more advanced than ordinary smart sensors. By detecting whether a door or window is open or closed, it provides an instant update to your smartphone through the Mi Home App, ensuring you stay informed no matter where you are. Parents, renters, office workers, and homeowners benefit greatly from this real-time monitoring capability, especially when they want to keep track of children, protect valuable items, or maintain home security while away.

One of the most important features of the Mi Door and Window Sensor 2 is its ability to work with a Bluetooth 5.1 gateway. When connected, every open and close event is recorded in detail. You are not only getting notifications, but also a complete timeline of activity. This is especially useful when monitoring areas like storage rooms, balconies, baby safety doors, refrigerators, wardrobes, or office drawers where important items are stored.

The addition of a light sensor takes smart automation to the next level. Unlike previous generations, this model can detect ambient brightness, allowing the sensor to work as part of intelligent scenes. For example, you can set your smart lights to automatically turn on when you open the door at night, or turn off once the door is closed and the room is bright enough. This combination of motion-less automation and light-based logic makes the Mi Door and Window Sensor 2 a key component for anyone designing a smarter and energy-efficient lifestyle.

Installation is extremely simple. Because of its compact size and lightweight body, the sensor can be mounted using the included adhesive backing. There is no drilling, no wiring, and no professional installation required. As long as the two parts are aligned properly within the recommended 18mm gap, the sensor works flawlessly. This makes it a perfect choice for renters and homeowners who want non-damaging installation options.

Managing the device is effortless thanks to deep integration with the Mi Home (Mijia) App. Through the app, you can check live status, monitor entry logs, adjust smart scenes, set timed alerts, manage notifications, and connect the sensor to other Xiaomi smart home devices like lights, cameras, smart speakers, and alarms. The sensor also works with the Xiaomi AI Speaker, allowing voice-activated notifications and control features.

Powered by a long-lasting CR2032 coin-cell battery, the Mi Door and Window Sensor 2 is designed for months of maintenance-free operation. Its low-energy Bluetooth 5.1 wireless protocol ensures excellent battery efficiency and stable performance throughout daily use. With a compact size of 34 × 32.7 × 14.5 mm, the device is barely noticeable, yet powerful enough to play a major role in protecting your home.

The sensor is engineered to withstand a wide range of environments with an operating temperature of –10°C to 50°C, and humidity tolerance reaching up to 95% RH, making it suitable for homes in Bangladesh where temperature changes and humidity levels are common. These durability features ensure long-lasting performance even in kitchens, balconies, or near open windows.

For customers in Bangladesh searching for smart home gadgets that offer high value at an affordable price, the Mi Door and Window Sensor 2 stands out as a top choice.
