In embodiments of motion sensor controlled lighting, a through glass motion detection lighting system may be contemplated comprising a motion sensor and a method to wirelessly transmit a control signal through the glass based on the motion detected signal to a lighting device on the other side of glass comprising of a light source, a wireless receiver and logic to decode the control signal. In some embodiments, the method for communication through glass to lighting device on other side may include infrared, radio frequency or LED pulsing. In alternate embodiments, the medium the motion detection indication is transmitted through may not be glass but is instead plastic, drywall, wood, cement or similar materials used in building and construction. In some embodiments a mounting mechanism such as suction cups, adhesive tape, screws or similar may be used to mount the motion sensor and wireless lighting device on opposite sides of transmission medium. By way of an example, a through the glass motion detector system may comprise a PIR sensor, a coin cell battery, an low intensity narrow angle LED that emits light upon detected motion and a housing including a suction cup to mount to a glass surface. On the opposite side of the glass is a wireless lighting device that has a light sensor selected to detect energy in the wavelength of narrow angle LED, a second light source for illuminating an area on that side of the glass, a wireless power source such as a battery and a housing with a mounting mechanism such as a suction cup to attach to the glass. In alternate embodiments, the inside device may be mounted anywhere and glass mounted PIR sensor could be effectively a “remote PIR sensor”.
