How do you wire security light with sensor?
You wire a security light like any other light. The sensor is generally part of the light and provides an "auxiliary" switch to detect movement and switch on the light, usually only after dark. The regular light switch for the security light should be left "on" at all times and labeled or enclosed to prevent being accidentally turned off. The sensor will not work, and the light will not go on, if the regular light switch it not on. Many modern units allow you to "lock" the motion sensor on by using the regular light switch to turn off the circuit and quickly turn it on again. This makes the light stay on until morning, when the photocell will turn it off and reset the lock, even without any motion detected.
Who invented the motion detector?
After much more research the real answer I believe is here: http://www.patentstorm.us/patents/4703171/fulltext.html I have found that William Kahl invented the infrared motion sensor for burglar alarms first and then he sent in an application for the infrared light switch motion sensor in 1985. There had been other motion sensor light switches but this specific infrared motion sensor (PIR) is the one that is most used today residentially and in companies as well.
