The MS361 uses Microwave technology (5.8GHz) for the sensor thus detecting even the slightest movement in its detection zone to turn lighting on and off based on occupancy. The MS361 should be installed indoors and mounted on the ceiling at a height of around 2.5m, the detection range (radius) can be adjusted to a minimum of 3m and a maximum of 12m. The light can be set to stay on for any period of time from approximately 10 seconds to a maximum of 12 minutes. Major Tech Microwave Motion Sensor Light Switches can penetrate through doors, glass and thin walls which means these security sensors can be placed behind objects. They are easy to install, provide high probability of detection and are low nuisance alarms. MS361 motion sensors can save up to 60% of lighting energy costs dependent on occupancy. Application: Ideal for home use and in educational and commercial properties Detects through doors, glass panes or thin walls Features : 360° Detection Field Automatically turns on lights when motion and body heat is detected 2 – 2000 LUX (Adjustable) Installation height 1.5 – 3.5m (wall) / 2-10m (ceiling) Identify day and night automatically Time-delay and ambient light adjustment SENS adjustable Detection distance 5 – 15m (wall) (adjustable) / 2 -8m (ceiling) (radius / adjustable) Power consumption 0.9W Detection moving speed 0.6 – 1.5m/s
