Description:
The 10.525 GHz microwave motion sensor offers a significant advantage over traditional infrared (IR) sensors by employing the Doppler effect to achieve superior motion detection. Instead of passively sensing heat signatures, this active sensor emits microwaves and intelligently interprets frequency shifts in the reflected waves caused by moving objects. This key distinction provides exceptional sensitivity to a broad spectrum of microwave-reflective materials and, crucially, eliminates the influence of ambient temperature on sensor readings. This inherent reliability and versatility make it an indispensable component in numerous industrial, transportation, and civil applications. From accurately gauging vehicle speed and monitoring liquid levels to enabling hands-free automatic doors and washing systems, ensuring precise material detection in production processes, and enhancing driver safety with car reversing assistance, this microwave sensor delivers dependable performance in diverse and demanding environments.
