DFRobot SEN0395 24GHz mmWave Radar Human Presence Sensor 9m
Low Stock, 1 left
Product Description
DFRobot SEN0395 24GHz mmWave Radar Human Presence Sensor detects moving, micro-moving and stationary human presence at distances up to 9m. Unlike PIR-only presence sensing, the mmWave radar can detect very small body movements and stillness, making it suitable for occupancy sensing, smart lighting, HVAC control, security and intelligent automation.
The compact 24 × 28mm module uses 24GHz FMCW/CW radar, supports UART plus GPIO switching output, operates from 3.6–5V and provides a broad 100° × 40° sensing beam.
