| Abstract: | The paper introduces the design of an intelligent digital pressure meter used to measure the gas pipe pressure. The design is mainly made by MPX5500DP Pressure Sensor, LM3S 1138 microcontroller, and PTR8000 wireless communication module. The signal, measured by pressure sensor, is sent into LM3S 1138 microcontroller, after it has been decoupled and filtered. Then, after some disposals, such as the A/D switch, the data can be got, it is displayed by the LCD and the disposed data will be sent to the upper monitor. Thus, dispose, store and monitor the pressure data of gas pipe in real time. The design improves the convenience of pressure measuring, decreases the cost, and reduces the energy consumption, so it has certain value of reference. |
