What is the mmWave radar sensor?
Millimeter radar technology is a non-contact means of detecting objects, providing the distance, speed, and angle of these objects (in our case, people). mmWave sensors transmit signals with wavelengths in the high-frequency range between 24GHz and 300GHz, also known as the millimeter (mm) range.
Precise Motion and Stillness Detection
Compared to other human presence sensors such as PIR sensors, infrared sensors, and ultrasonic sensors, mmWave sensors offer the ability to sensitively detect both activity and stillness. They also possess strong interference immunity, making them less sensitive to factors such as temperature changes, variations in ambient light, and environmental noise. The sensor can quickly and sensitively detect the presence of a person, whether sitting, sleeping, or in motion.
Exceptional Sensitivity
The use of millimeter technology allows these sensors to utilize high-frequency electromagnetic waves that propagate at speeds comparable to light in the air. As a result, they are widely recognized for their remarkable accuracy and sensitivity. The sensors are extremely effective in various fields, such as smart homes and object tracking, enabling precise determination of an object's location within the environment.
Compact Size and Easy Integration
With dimensions of 24*28mm, about the size of a 25-cent coin, mmWave human presence sensors feature a compact form that facilitates their use and smooth integration. Their small size, combined with a square design, allows for easy integration into various devices and systems.
Extensive Application
These sensors can also be interconnected with other sensors, such as light and temperature sensors, facilitating applications in smart homes for controlling lighting and air conditioning. Their universal integration capabilities can be leveraged in a wide range of applications, including robotics projects and logistics monitoring.
