Compared to other sensors such as infrared and ultrasonic sensors, the C4001 (25m) millimeter wave sensor has the advantage of detecting both static and moving objects. It also has a relatively strong anti-interference ability, making it less sensitive to factors such as temperature changes, light fluctuations and ambient noise. Compared to conventional pulse radar, the FMCW radar continuously measures the distance of objects. Through the effect, it can also get information about the speed of the target objects. Therefore, it is ideal for applications where monitoring the movement of target objects is required. The FMCW radar is a radar system based on a frequency-modulated continuous wave. Unlike traditional pulse radars, the FMCW radar continuously emits a series of continuous signals whose frequencies gradually change while simultaneously receiving the reflected signals. The analysis of the received signals allows the measurement of parameters such as distance, speed and angle. Whether a person is sitting, sleeping or moving, the sensor can detect his presence quickly and with sensitivity. Distance and Speed Detection The C4001 millimeter wave presence sensor (25m) uses frequency modulated continuous wave modulation (FMCW) to measure distance and speed. Its maximum range is 25 meters for distance and 0.1 to 10 meters per second for speed. In addition, the FMCW radar allows continuous frequency sampling and thus offers a higher measurement resolution. Since it does not have to wait for the echo signal to return, it is suitable for applications that require real-time monitoring and tracking of target objects.
