Motion sensor/photoelectric light sensor plug-in receptacle
First Claim
1. A motion sensor/photoelectric light sensor device for electrically energizing non-motion sensor equipped electrical devices, said sensor device having:
- input means for connection to a source of electrical energy, output means for connecting electrical energy from said source through a control to said electrical devices, a first means to detect the presence of moving infrared radiation sources, a means to detect ambient light, a second means to compare the level of ambient light with a preset threshold, and a third means to electronically override the said first means and said second means;
said control having modes of operation which comprise;
a first operation mode wherein said output means is energized upon the detection of a moving infrared radiation source and remains energized for a predetermined period of time after cessation of said moving infrared radiation detection, provided the ambient light intensity is below a predetermined level;
a second operation mode wherein said output means is energized when the ambient light intensity is below a predetermined level regardless of detection of a moving infrared radiation source; and
a third operation mode wherein said output means is energized by moving infrared radiation detection regardless of ambient light level, wherein each of said operation modes is controlled by at least one signal generated by at least one sensor selected from said first means and the ambient light detecting means.

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.
