View Light Sensor Switch Wiring Diagram Background. Here is my wiring diagram ( third photo) and instructions connect red sensor wire to light's black wire. As soon as one of the transistors is blocked the lamp there is no need for external power supply because the light sensor switch is powered directly from the 220v mains.
Infrared PIR Motion Sensor Switch Infrared Sensor Detector ... from ae01.alicdn.com Ambient light detection lights turn on only if natural light in room is low. In this circuit pir (passive infrared ) sensor is used which is used as when any person, animal or any object comes in the range of the sensor. Transistor is used as a switch here.
The light switch should always remain in the on position for the photocell to operate automatically.
Ideal for kitchen, furniture, mirror, etc. Wiring devices & light controls. Two sensor shell can be chosen. Shed 12v solar lighting system.
