The 24GHz mmWave Sensor for XIAO - Human Static Presence is a sophisticated expansion board designed for the XIAO series. This high-sensitivity mmWave radar sensor is integrated with an antenna and operates based on the FMCW (Frequency-Modulated Continuous Wave) principle. This technology, coupled with advanced radar signal processing and precise human body sensing algorithms, enables the sensor to accurately identify human bodies in both motion and stationary states.

The sensor exhibits a high level of sensitivity, not only to moving human bodies but also to static individuals, micro-movements, and individuals in sitting or lying positions. This comprehensive human-body detection capability makes it an ideal choice for a variety of applications, including human-body sensor light control, life safety protection, smart home appliances, and intelligent security.

One of the key features of this sensor is its multi-level intelligent parameter adjustment. This can be done using Bluetooth or a serial port, providing flexibility to adapt to varying environmental conditions and scene changes. Furthermore, it supports direct parameter configuration through an app, eliminating the need for a serial port connection.

The sensor boasts a wide detection angle and long sensing distance. With a field of vision of up to 60 degrees, it can detect movement from a wide angle. Additionally, it can detect objects up to 5 meters away.

Another notable feature is its excellent shell penetration and aesthetic enhancement. The sensor can work discreetly inside the product's casing without the need for surface perforations, thereby maintaining the aesthetics of the product.

The sensor operates at a frequency of 24 GHz~24.25 GHz and requires a DC 3.3 V operating voltage. It has a power supply capacity of more than 200 mA and an average operating current of 79 mA. The sensor is designed to operate in a wide range of ambient temperatures, from -40 to 85 °C, and has compact dimensions of 18 x 22 mm.
