5.8GHz Microwave Radar Sensor Module

The 5.8GHz Microwave Radar Sensor Module is an advanced motion detection sensor that uses Doppler radar technology to sense motion by detecting changes in microwave reflection caused by moving objects. Unlike traditional PIR (Passive Infrared) sensors, this module can penetrate non-metallic materials such as plastic, glass, and wood, making it perfect for concealed installation in smart home systems, IoT automation, and security devices.

Operating at a 5.8GHz frequency band, this radar sensor offers wide coverage and high reliability. It is capable of detecting motion within a 5–9 meter range, with 360° omnidirectional sensitivity, unaffected by temperature or environmental light conditions.

Compatible with Arduino boards, Raspberry Pi, and NodeMCU modules, it’s perfect for building automatic lighting systems, door sensors, presence detectors, and anti-theft alarms. The module is compact, power-efficient, and ideal for both DIY electronics and professional automation setups.
