High-frequency 5.8 GHz microwave sensor detects motion up to 12 metres with 180° wall coverage to switch lights and appliances automatically, saving energy. Fine-tune performance using adjustable sensitivity (1–8 m) and lux control (0–2000 lux) for accurate activation only when needed. Timer delay from 10 seconds to 12 minutes prevents wasteful operation while supporting 1200 W/300 W rated loads for common lighting and appliance setups. Compact wall‑mount design, simple AC wiring and durable build make installation fast and reliable across corridors, bathrooms and garages.
