Dual‑Mode Microwave & PIR Motion Sensor Switches

These dual‑detection sensors combine PIR infrared and Doppler microwave technology to solve direction‑related detection failures. The PIR infrared sensor responds best to lateral / tangential human movement, while the microwave sensor detects head‑on frontal movement based on the Doppler effect.

Complementary directional sensing enables multi‑angle human motion capture, delivers higher detection resolution and greatly reduces missed detections. Ideal for indoor spaces requiring reliable all‑direction motion triggering for automatic lighting control.
