Abstract Now,with the continuous development of science and technology, research anddevelopment people on the Android system is also used in various fields. Especially in theindustrial field, Android system has been developed into the field of human-machineinterface applications, to act as a host computer, data input and display, butt and lowercomputer data communication. The program can effectively solve the traditional controlsystem to achieve the monitoring role of the PC software only runs on PC-side limitations.Temperature measurement and control is one of the industrial production process of atypical application of the principle, temperature control is the temperature and set thetemperature detected by comparing the output control signal after operation to adjust thetemperature control device, in order to achieve a temperature control. However, to achievethe temperature acquisition and control and inseparable from the single chipmicrocomputer, the required temperature sensor, display, and so on a series of hardwarecircuit components. In this paper, the design of the a based on AT89C51 temperaturedetection and alarm system. This system is using the single bus digital temperature sensorto realize the temperature monitoring and control. Implementation of automatictemperature control is conducive to people to improve work efficiency and product qualityof production. In this paper gives me this system hardware design and circuit design arealso given for the program design of the overall thinking and concrete implementation. Theexperiments show that, the system test High precision, strong anti-interference ability,timely and accurate alarm, with a certain reference value.So the design is based on AT89C51 to the next crew, combined with Android tabletdisplay and data entry PC, temperature control system design. It is bound to have a positivepractical significance and broad application prospects.
Keywords: Digital temperature sensor, AT89C51 single chip microcomputer,temperature control, Android software, Bluetooth.
