HMMD-mmWave-Sensor - radar sensor of human presence

Description

24GHz Doppler Radar Module with Transceiver is an advanced device that enables precise distance measurement, detection of movement direction, and speed measurement of a moving object. The module utilizes the physical phenomenon of the Doppler effect, analyzing the frequencies of waves generated and received by the device. The interface on the board allows advanced users to customize the radar's operation according to their needs. The module communicates via a UART interface and is powered by 3.3V, making it ideal for various applications.

The radar uses Frequency Modulated Continuous Wave (FMCW) technology to detect and identify movement, stillness, and micro-movements of the human body. The module combines radar signal processing with precise detection algorithms, allowing sensitivity configuration for each range independently, improving its resistance to interference. It is based on the AIoT mmWave Sensor SoC S3KM1110 and features built-in high-performance 24GHz 1T1R antennas. The built-in MCU and human micro-movement detection algorithm enable accurate detection of movement and stationary people. The module offers a UART communication protocol and allows configuration of detection range, sensitivity, and no-report delay, making it easy to use. It also supports UART and GPIO outputs, enabling connection to mainboards such as Raspberry Pi or Arduino. It is compact, features low power consumption, and is easy to integrate, making it widely applicable in AIoT (Artificial Intelligence of Things) scenarios such as Smart Home, intelligent security systems, Smart Business, and intelligent lighting.
