WebDec 26, 2024 · How Photo Eye Sensors Work. There are two photo eye sensors fixed six inches above the ground in the garage door. These are placed either side of your overhead door. These two eyes develop the beam in their path. Thus, the sender sends a beam, and the receiver receives to operate it. In case, you or anything interrupts the beam … WebJan 1, 1993 · Photo eyes in sensors will usually have an emitter eye and a receiver eye opposite to each other. Check if the led lights blink when closing the door. Blinking/flickering or no lights indicate the sensors are not aligned. When adjusting sensors. Watch the blinking of colors and intensity of color. Try to get the color bright.
