Occupancy sensor based on 24 GHz millimeter wave technology with FMCW, enabling precise detection of people, measuring distances up to 25 m and movement speed. Thanks to high resistance to environmental interference, it works reliably in conditions such as dust, light or temperature changes, outperforming traditional PIR and ultrasonic sensors. Compact size and installation flexibility make it perfect for intelligent lighting, security systems and building automation. DFRobot SEN0609
The C4001 presence sensor module uses 24 GHz millimeter-wave technology to accurately detect human presence, as well as measure distance and movement speed. Based on FMCW (Frequency Modulated Continuous Wave) technology, it can simultaneously measure distance and speed within a range of 0.1 to 10 m/s. The presence detection range extends up to 16 meters, while movement and distance measurement can reach up to 25 meters.
Compared to traditional infrared or ultrasonic sensors, the C4001 stands out with its ability to detect both stationary and moving objects. It offers high reliability thanks to strong resistance to environmental interference such as dust, light, temperature changes, and noise. This makes it an excellent choice for smart lighting systems, building automation, presence monitoring, and security applications.
Its compact size allows for easy integration into IoT systems and small electronic devices. The sensor supports various installation orientations—including ceiling, floor, horizontal, or angled mounting—providing deployment flexibility. It can detect a person whether they are sitting, sleeping, or moving, ensuring high sensitivity and real-time performance.
