Key Takeaways
- Xiaomi has introduced the Mijia Smart Bathroom Heater P1 Human Sensing Edition in China.
- The device uses a 24GHz radar system to detect human presence and adjust functions accordingly.
- It features a 3,000W graphene heating element and dual DC motors for simultaneous heating and exhaust.
Xiaomi has expanded its smart home product range with the launch of the Mijia Smart Bathroom Heater P1 Human Sensing Edition in China. This innovative device combines multiple functionalities, including lighting, heating, and exhaust, into a single unit designed to enhance user convenience.
The primary feature of this new heater is its built-in 24GHz radar system, which detects whether someone is inside the bathroom. The system automatically adjusts the hardware based on the presence or absence of a person, ensuring that lights turn on when needed and exhaust fans run during use, then switch off after the user leaves.
In contrast to traditional infrared motion sensors, which can fail if someone remains still for too long, Xiaomi’s 24GHz radar sensor is designed to continuously detect human presence. This feature helps prevent false triggers caused by people walking past an open bathroom door, making the device more reliable and efficient.
The Mijia Smart Bathroom Heater P1 Human Sensing Edition also boasts a powerful 3,000W graphene heating element, which can quickly warm up the bathroom space. Additionally, it includes a variable frequency control system that adjusts power output to maintain a selected temperature rather than running at full power continuously.
To ensure even heat distribution, the device features an oscillating louver that swings between 60 and 90 degrees, pushing warm air downward toward the floor. This design helps remove moisture and odors while maintaining a comfortable environment.
For added convenience, the heater connects with Xiaomi’s Mi Home app and HyperOS ecosystem, allowing users to set schedules, control the device through the app, and use voice controls. The package also includes an IPX4-rated water-resistant wireless wall switch for physical control points without requiring new wiring.
The crowdfunding price for the Mijia Smart Bathroom Heater P1 Human Sensing Edition is approximately $148 in China. Xiaomi has not announced any plans to launch this device globally, leaving its international prospects uncertain at present.
