Abstract
A motion sensor and photoelectric light sensor activated plug-in type electrical receptacle which conveniently plugs into a standard power outlet is disclosed. The device allows non-motion detector and/or non-photoelectric equipped devices to function as motion sensor and/or photoelectric sensor operated devices. The device has motion and photoelectric switches permitting customized applications. The device can be used with any wall or ceiling mounted electrical outlet to automatically turn on and off other plug-in type electrical devices such as night lights, radios, heaters, and thereof, when presence of people and/or pets is detected. This device conveniently plugs into any wall power outlet by means of two or three prongs without requiring new wiring or rewiring of the existing electric circuit.
