The EcoSavers® Microwave Lampbase E27 is a clever device which uses microwave to detect movements.
This product switches on the light in dark conditions – due to the integrated daylight sensor – when the microwave detects movements. This works through lampshades, but even walls.

Detection range radius 3 – 7 metre.
