A MEMS air pressure sensor system is proposed in the paper, which can monitor the air pressure by means of measuring the discharge time of the sensor. The system contains two parts: the MEMS air pressure sensor and the data acquisition system. The MEMS air pressure sensor is an enhanced pizeoresistive pressure sensor. The data acquisition system contains a time-to-digital part, which measures time interval by using of the propagation delays of logical gates. The time-to-digital part can measure the resistors’ discharge time and turn it into digital output, when the resistors on the air pressure sensor are connected to a capacitor which is full of charge. The discharge time is only related to the resistor, and then the pressure measurement is changed to time measurement. The digital output is shown through a liquid crystal display screen.

Weather Observation

Data acquisition system for barometric capacitive pressure sensor with high accuracy is present. The precision of the data acquisition system is less than 1fF, which improves the pressure sensor with high accuracy of 0.1hPa in the pressure range from 5hPa to 1080hPa. The data acquisition system consists of an AD7746 chip, an ATmega16 microprocessor, a 1602 LCD display and a pair of wireless modules. The capacitance data acquired by the AD7746 are transferred to a host computer using RS232 port via wireless module and display on the LCD in real-time. Preliminary results obtained from experiments show that this system fulfills the requirements of the weather observation and can be used in upper-air weather detection applications.

Pressure of tire is measured using Tire Pressure Monitoring System (TPMS) model. By measuring the tire pressure, the fuel can be saved and the vehicle can be controlled in better way. The real of tire pressure can be monitored in real time and if the pressure of the tire goes out of the threshold this system gives alarm and alert the driver to ensure the driver safety, hence the life of the driver can be safeguard and pre-warn the driver and passengers. TPMS consists of an electronic unit that sense the tire pressure displays it to user in a LABVIEW platform. This unit includes a pressure sensor and Data Acquisition System. The output of the pressure sensor is given to the Data Acquisition System. Then the DAQ is interfaced with PC to display the tire pressure in the dashboard using the LABVIEW platform. If the tire pressure crosses safe pressure level a warning is generated
