The Major Tech MS361 is an indoor microwave motion sensor for automatic lighting control and presence detection in homes, offices, schools, and shared spaces. Unlike traditional PIR sensors, it detects subtle movement and body heat through doors, glass, and thin walls, making it ideal for enclosed areas where standard sensors may struggle.

With 360° ceiling or 120° wall mounting, the MS361 delivers broad coverage with adjustable lux sensitivity, time delay, and day/night modes. It supports LED, CFL, and incandescent loads up to 600W, and is rated for indoor use only.
