The DFRobot Mmwave - 24GHz Human Presence Sensing Module (6 m) is a highly sensitive radar module designed to detect human presence within a specified area. It employs frequency-modulated continuous wave (FMCW) technology, combined with radar signal processing and an accurate human sensing algorithm, to discern both moving and stationary human targets. This module is also capable of calculating auxiliary information, such as the distance to the target.
The performance of this radar module is not affected by environmental factors such as temperature, brightness, humidity, or light fluctuations. The FMCW radar's ability to penetrate materials allows the module to function effectively even when enclosed in a shell, without the need for openings.
