5.8GHz Microwave Radar Module

The 5.8GHz Microwave Radar Module is a highly sensitive motion and presence detection sensor designed to identify human movement and occupancy using microwave Doppler radar technology. Operating at 5.8GHz, the module continuously transmits electromagnetic waves and analyzes reflected signals to detect movement within its coverage area. Unlike conventional PIR sensors that primarily detect large body movements, this radar sensor can detect subtle motions such as breathing and micro-movements, allowing it to determine human presence even when a person is sitting, resting, or sleeping.

Featuring high sensitivity, strong anti-interference capability, and reliable performance, the module provides detection results through both serial communication and digital I/O output signals. Its compact size and easy integration make it suitable for smart lighting, security systems, home automation, building management, and energy-saving applications. The sensor performs effectively in various indoor environments where accurate occupancy and motion detection are required.
