While photocell sensors detect ambient light, motion sensors detect and react to physical movement. Usually, they combine several methods to eliminate false positive motion sensing and enhance coverage. WebDusk to dawn photocells operates by sensing the level of ambient light. They are maintenance-free, and energy-efficient lighting that also helps provide safety and security. A 120-277V line voltage is used to hardwire photocells. Dusk to dawn photocells are used to control electrical circuits and activate outdoor lighting fixtures. little beauty clinic
