Abstract

Barometer is an equipment that uses the pressure-sensitive components to directly convert the pressure to be measured into current or voltage signal, which is then processed and controlled by the single-chip machine for real-time display. The internal core element is the pressure sensor, which plays an important role in monitoring pressure, controlling pressure changes, and measuring physical parameters. The use of single-chip microcomputer for processing and control has a powerful control, small size, high integration and other advantages. In this design, first the pressure and temperature sensor BMP085 is used to collected the corresponding simulation signals of the environmental pressure and the temperature. This simulation signal is then processed by the signal conversion module within the pressure and temperature sensor. Finally, it is displayed on the LCD display module under the control of the STC89C51 single chip machine. In addition, the system can re-set the threshold by the key circuit and be stored in the memory module, and it can compared the actual value and the set threshold value to determine whether the actual value exceeds the limit before carrying out the sound and light alarm. It is verified through experiment that this design is safe, stable and economical, etc.
