How mmWave Presence Sensors Solve the Challenge of Smart Bathroom Lighting

Bathrooms are one of the most challenging spaces for presence sensors. PIR often fails due to stillness, glass partitions, and steam, leading to missed detections or false triggers. mmWave radar overcomes these issues with micro-motion sensing, through-glass detection, and resistance to humidity—ensuring lights respond reliably to real presence. This article explores common problems, best installation practices, and how Linpowave’s mmWave presence sensors deliver smarter, more energy-efficient bathroom lighting.
