ABSTRACT
This system used STC89C52 SCM to control the infrared emission diode to transport the audio to the infrared receiving diode wirelessly in the short distance. The infrared emission diode sent signals. The wireless signals done the square wave modulation with the signals with its frequency as high as 38 kHz generated by the SCM. The infrared receiving diode demodulated the received signals and then done the signals transduction. The system used one channel to transport the value of the temperature from the infrared emission based on the 38 kHz to infrared receiver wirelessly. And it used another channel to transmit audio signals from the infrared to the infrared receiver tube under the control of the transistor. Compared to other wireless transmitting equipment, the infrared tubes had the low power consumption, low price, the moderate transmission distance, particularly suitable for short-distance transmission. The system has the widespread application in the remote control devices in the smart home.
