Remote control infrared detection circuit The circuit in this figure can transport the signal of the detected target in long distance. The PC-1 is a pair of infrared diode and phototransistor. When the object obstructs the light of diode exposure to the photo-transistor, the photo-transistor will be in the cut-off state, and the signal is amplified and added to the load through the second pair of infrared diode and phototransistor. The second pair of infrared diode and phototransistor has the failure insurance effect.
