【正文】 紅外接收模塊電源供電5V圖1 系統(tǒng)整體框圖 系統(tǒng)工作原理紅外通信是利用950nm近紅外波段的紅外線作為傳遞信息的媒體，即通信信道。數(shù)碼管具有接線簡單，成本低廉，配置簡單靈活，編程容易，對外界環(huán)境要求較低，易于維護(hù)等特點。而且僅需5V單電源供電，功耗更低。故選方案一。Abstract:With the advancement of technology, wireless munication technology has been an unprecedented development, and infrared wireless data munications relative to the radio data munication with low power consumption, low price, low electromagnetic interference, high security, etc., is currently developing rapidly, especially in in the shortrange wireless data munication has been widely used. Especially with the coding and modulation technology, infrared wireless data munications increasingly high data rates, as many mobile devices, office equipment, and handheld devices indoor wireless data munication is an important way. The system munication device via infrared light and ambient temperature voice signal wireless transmission out, the receiving port display temperature and outgoing voice signal from the headphones. The ambient temperature detected by the STM32 MCU, voice signals and digital signals can be transmitted
