Motion Sensor Switch for Energy Saving Made of material, this infrared motion detector switch is designed to control lights and provide an energysaving solution. It uses infrared energy from humans to detect motion. As soon as you enter the sensor's detection area, the lights will automatically switch on. Once you leave the area, the sensor will power off the lights after a preprogrammed time, effectively saving energy. Day and Night AutoDetection: This sensor can automatically identify day and night conditions. You have the option to set it to work only at night or both day and night. With a 6 m range and 360degree detection angle, it can effectively detect motion in its surroundings. Convenient Installation and Use: This motion sensor switch can be used in various areas such as toilets, bathrooms (Zone 3 only), and any other place where energysaving is desired. It is widely used in situations where people often forget to turn off lights. Key attributes and performance: infrared motion detection, automatic on when occupied, automatic off after a preprogrammed time, 6 m detection range, 360degree coverage, day and night autodetection with selectable mode. Practical use scenarios: 1) Office or commercial toilets and bathrooms to reduce energy waste. 2) Home entryways, hallways, and utility rooms where lights are often left on. 3) Shops, clinics, or other traffic areas where lighting only activates when occupied.
