Title The development of wireless monitoring system based on Bluetooth transmission
Abstract Bluetooth is a short-range wireless communication technology has developed rapidly in recent years, can be used to replace the cables between different digital devices. Due to the development of electronic signal, measurement and control technology and digital technology, communication and network technology more and more closely related, Bluetooth technology is bound to its characteristics of low cost, wireless connection will be in the field of measurement and control have broad application prospects.
Around the development of wireless monitoring system based on Bluetooth purpose, the complete set is mainly done with Bluetooth wireless control system of digital temperature sensor DS18B20, the system innovation lies in digital transmission terminal adopts transparent transmission of wireless Bluetooth module, instead of the original serial cable transmission, data acquisition terminal data collection to the SCM processed by displaying the Bluetooth transmission module transmits to the terminal PC Bluetooth receiving module to PC， and can be controlled through the PC software design, so as to achieve the measurement and control of temperature.
Keywords Bluetooth MCU serial port: DS18B20 data transmission
