Human detection
Compared to other types of human presence sensors, such as infrared sensors, the C4001 (12m) millimeter wave presence sensor has the advantage of detecting both static and moving objects. It also has a relatively strong anti-interference ability, making it less susceptible to factors such as temperature changes, variations in ambient light, and environmental noise. Whether a person is sitting, sleeping, or moving, the sensor can quickly and sensitively detect their presence.
The differences between millimeter-wave presence sensor and infrared sensor
Distance and velocity detection
The C4001 (12m) millimeter wave presence sensor utilizes FMCW modulation for distance and speed measurement. It has a maximum detection range of 12 meters and a speed measurement range of 0.1 to 10 meters per second.
FMCW (Frequency Modulated Continuous Wave) is a type of radar system based on frequency modulation of continuous wave signals. Unlike traditional pulse radar, FMCW radar continuously emits a series of continuous wave signals with gradually changing frequencies while simultaneously receiving the reflected signals. By analyzing the received signals, measurements of parameters such as distance, speed, and angle can be achieved.
Compared to traditional pulse radar technology, FMCW radar can continuously measure the distance of an object. By utilizing the Doppler effect, it can also obtain information about the velocity of the target object. This makes FMCW radar suitable for applications that require tracking the movement of objects. Additionally, FMCW radar can achieve continuous frequency scanning, providing higher measurement resolution. Since it does not require waiting for the return of echo signals, FMCW radar is suitable for applications that require real-time monitoring and tracking of target objects.

2-RADAR A ONDES MILLIMETRIQUES – CAPTEUR DE DETECTION DE PRESENCE HUMAINE 24 GHZ (9 METRES) SEN0395
Introduction
What is a mmWave radar sensor?
Millimeter-wave radar technology is a contactless sensing technology for detecting objects and providing the range, velocity and angle of those objects (in our case humans). mmWave sensors transmit signals with a wavelength in the high frequency spectrum between 24GHz and 300GHz, also called the millimeter (mm) range.
Accurate Stillness and Motion Detection
Compared to other human presence sensors like PIR sensors, infrared sensors, and ultrasonic sensors, mmWave sensors offer the ability to sensitively detect both activity and stillness. They also possess robust anti-interference capabilities, making them less susceptible to factors such as temperature changes, variations in ambient light, and environmental noise. The sensor can swiftly and sensitively detect the presence of a person, whether they are sitting, sleeping, or in motion.
For example, in the context of a public smart restroom project, mmWave human presence sensors prove invaluable due to the complex and noisy environment typically found in such facilities. Despite these challenges, mmWave sensors can accurately and instantly monitor the occupancy status of restroom stalls. This optimization of layout and resource allocation in public restrooms enhances efficiency and improves the user experience.

Exceptional Sensitivity
By utilizing millimeter-wave technology, these sensors employ high-frequency electromagnetic waves that propagate at speeds comparable to light in the air. As a result, they are widely regarded for their remarkable accuracy and sensitivity. The sensors are highly effective in various domains, such as smart homes and item tracking, enabling precise determination of an object’s position within the environment. They can also penetrate certain objects, such as bed boards and clothing, enabling the detection of human presence or objects beyond physical barriers.
Small Size and Easy Integration
With dimensions of 24*28mm, approximately the size of a 25-cent coin, mmWave human presence sensors boast a compact form factor that facilitates ease of use and seamless integration. Their small size, coupled with a square design, allows for effortless embedding into various devices and systems. This enables the sensors to be widely employed in applications with space constraints or a need for compact designs without compromising performance or functionality.
For instance, mmWave human presence sensors can be integrated into fitness trackers or smartwatches. By detecting the body’s movements and posture, the sensors can provide accurate fitness data such as step count, distance traveled, and calorie consumption. These insights assist users in gaining a deeper understanding of their physical activity, enabling them to set and track fitness goals effectively.
