  • Two circuit lighting controller with sensors and RF remote
    Patent number: 9585232
    Abstract: A lighting controller comprising a single circuit sensor switch on a first circuit. At least one infrared PIR sensor is configured to cover 360 degrees. The at least one infrared PIR sensor is electrically connected to control the single circuit sensor switch. An acoustic sensor is electrically connected to control the single circuit sensor switch. A photo sensor is electrically connected to control the single circuit sensor switch. The photo sensor has an infrared remote controller and receiver for controlling the single circuit sensor switch. A second circuit sensor switch is on a second circuit that is connected to the first sensor. The second circuit sensor switch is configured to be connected to the single circuit sensor switch, the photo sensor, the acoustic sensor, and the at least one infrared PIR sensor so that the second circuit sensor switch further improves lighting efficiency.
