Product description: Human Presence Detection Sensor - mmWave 24 GHz sensor - DFRobot SEN0395
mmWave boards are a series of utility modules that allow you to make measurements related to human life activities . The Human Presence Detection Sensor is based on the Infineon mmWave FMCW industrial radar operating in the 24 GHz band. It is a sensor that detects the presence of a human at a distance of up to 9 meters, which also allows you to determine the presence of a static person - for example, a sleeping person.
The manufacturer has also prepared a detailed user's guide , which significantly facilitates the use of the module. Check!
What is mmWave Radar Sensor?
Millimeter wave radar technology is a non-contact technology for detecting objects and determining their distance, speed and their angle of inclination. The mmWave series sensors transmit wavelength signals in the high frequency spectrum between 24 GHz and 300 GHz, also known as the millimeter (mm) range. mmWave Radar Sensor performs measurements based on 24 GHz mmWave Doppler radar technology . It works independently of environmental factors - temperature, humidity, noise, airflow, dust, light and more. It is an ideal solution for individual applications, implementation of Smart Home applications, scenarios in a smart hotel or a broadly understood threat alarm.

The use of mmWave 24 GHz sensors
mmWave human presence sensors can be integrated with fitness trackers or smartwatches. By detecting body movements and posture, the sensors can provide accurate fitness data such as steps taken, distance traveled and calories burned. What's more, these sensors can be combined with other modules such as light sensors and temperature sensors, which allows the implementation of applications used to control lighting and air conditioning. Their versatile integration capabilities also favor a wide range of applications, including but not limited to robotics projects, smart home solutions and logistics facility tracking.
