Based on the FMCW principle: highly sensitive and immune to environmental interferences. Comprehensive Human Body Detection: The sensor not only detects moving human bodies with high sensitivity but also exhibits sensitivity to static individuals, micro-movements, as well as individuals in sitting or lying positions. Multi-Level Intelligent Parameter Adjustment: Adjusted using Bluetooth or a serial port, providing flexibility to meet varying environmental conditions and scene changes. Additionally, it supports direct parameter configuration through an app, eliminating the need for a serial port connection. With a field of vision of up to 60 degrees, the sensor can detect movement from a wide angle. Furthermore, it can detect things up to 5 meters away. Has good shell penetration, allowing it to work discreetly inside the product's casing without the need for perforations. Product Description: The 24GHz mmWave Sensor for XIAO - Human Static Presence is an extension board designed for the XIAO development platform. It serves as a highly advanced human body sensing module that utilizes FMCW (Frequency-Modulated Continuous Wave) technology to detect human targets within a designated space. Powered by sophisticated radar signal processing and precise human body sensing algorithms, this module achieves exceptional sensitivity in detecting human presence, accurately identifying both moving and stationary states. It also provides auxiliary information such as target distance calculation. Primarily deployed in indoor environments, this product offers real-time detection of moving or micro-moving human bodies.
