The DFRobot SEN0395 motion sensor uses 24 GHz mmWave radar technology for contactless detection of human presence, whether moving or stationary. It detects presence at distances of up to 9 m and can detect people behind certain obstacles, such as bed boards and clothing. Its operation is unaffected by snow, fog, changes in temperature and humidity, dust, light, or noise.
The I/O inputs and outputs support switch control, while the serial port supports data input and output. Its compact, square design makes it easy to integrate into space-constrained systems, such as smart home applications and robotics projects.
