Abstract At present, It is extremely necessary to measure the temperature and barometric pressure in weather monitoring, food storage, industrial and agricultural production, military and industrial charges and so on many domains。 And accurate parameter measurement results have a substantial effect on following work。 Therefore, to build a secure and reliable high-precision temperature and pressure monitoring system has important social and economic significance。
The main task of this project is to complete a high-precision temperature and pressure monitoring system。 Through a comprehensive analysis of domestic and international status of temperature and pressure measurement technology, This subject proposed a design schemecombined with microcontroller technology and Bluetooth wireless communications technology, and Successful construction the corresponding hardware circuits, software systems。
Hardware circuit use STC89C52RC as main controller, extending temperature air pressure measurement module, bluetooth wireless transmission module and other related application modules。 Through the control of the microcontroller, so that each module is properly complete the corresponding operational tasks, and form an orderly and efficient whole。 Software design is modular, including the main program, temperature and pressure collection procedures, Bluetooth wireless and PC design。the system uses Android smartphone as a remote monitoring of this PC。
