This system adopts the infrared transmitting tube and infrared receiving tube for analog signal and digital signal can be transmitted infrared communication. In a voice infrared simulation system,the voice signal conversion to electrical signals as the analog signal sent directly,at the receiving end through integrated amplifier LM386 chip processing,will eventually electrical signals back into sound signal,so as to realize the infrared communication. In the infrared digital communication system,by adding all the digital channel,using digital temperature sensor DS18B20 for temperature acquisition in real time,and STC89C52 microcontroller control to digital signal,finally at the receiving end through the gate input single-chip microcomputer by 1602 to show.
