The highly anticipated Xiaomi Door and Window Sensor 3 has officially kicked off its crowdfunding campaign, priced at an attractive 44 yuan. Following the crowdfunding period, the product will hit the market with a suggested retail price of 49 yuan.

This latest iteration of the sensor showcases significant upgrades, notably replacing the traditional Hall sensor with a cutting-edge tunnel magnetoresistance sensor. This enhancement results in a faster response time, reduced power consumption, and fewer missed detections, ensuring a more reliable and efficient user experience.

Powered by a CR2032 button cell battery, the Xiaomi Door and Window Sensor 3 offers an impressive battery life of up to 3 years, based on an average of 30 daily openings and closings. When the battery runs low, the Mi Home APP will promptly send reminders to keep users informed.

In addition to its core functionality, the sensor introduces new features such as daily opening count and tracking of open/close durations, catering to users' diverse needs. Notably, the light sensor has been removed to streamline the design and focus on essential functions.

Designed for ease of use, this compact and lightweight device can be effortlessly attached using adhesive. To prevent incorrect installation, it is clearly marked with a magnetic induction side identifier, ensuring hassle-free setup.

For remote viewing of the open/close status and history, the sensor requires a Bluetooth Mesh gateway. The Mi Home APP will also send alerts for abnormal openings or when the door/window is left open for an extended period, enhancing security and peace of mind.

Furthermore, the Xiaomi Door and Window Sensor 3 supports Xiaomi HyperOS Connect, enabling seamless integration with various automated scene linkages. This feature opens up a world of possibilities for smart home automation, allowing users to create personalized and convenient living spaces.
