he method of temperature data acquisition has penetrated into various aspects of life. In industrial sites, due to the harsh production environment, workers cannot stay on site for long to observe whether the equipment is operating normally. In agricultural production, temperature monitoring in greenhouses or grain storage management involves manual sampling in different areas, which is labor-intensive and has low reliability. In daily life, an intelligent temperature acquisition and control system can better improve people's living environment. Wireless communication technology has the characteristics of small size, simple hardware circuit, convenient and flexible control, and intelligence. Compared with other RF infrared transmission modules, infrared transmission and reception tubes have the outstanding characteristics of low power consumption, low price, high efficiency, moderate transmission distance, small volume, and simple encoding and decoding technology. It has been widely used in remote control devices for household appliances, agricultural greenhouse temperature management, and industrial site temperature acquisition. This paper uses a temperature data transmission - infrared temperature audio transmission system based on 38KHz infrared emitting tube and infrared integrated receiving head. Keywords: Wireless Communication; Temperature Acquisition; Encoding and Decoding Technology.
