The infrared receiving and motor driver circuit is as shown in figure 1, when there is no one, the infrared receiver receives the infrared beam which is from the other side. You can fix it one the wall by using the 60mm guide tube which can insert the infrared tube exactly (figure 3), the height is appropriate, and it aims at the opposite receiver, so the infrared ray is not easy to interfere another receiver. The installation method is as shown in figure 4. The signal is amplified and filted by BG6, BG7 and CR to output the low level, the BG5 cuts off.
