Abstract : The area of physical quantity processing in recent sensor applications demands for high accuracy, low distortion, fast response and low power consumption. The pressure processing is one of the most important issues for designers. There exist many problems, which have to be solved to measure relative and absolute pressure. Measuring the signal from sensor with low amplitude and to remove the noise is difficult process. This project deals with a custom based Integrated Measurement Unit (IMU), which serves as processing device for MEMS based pressure measurement. The IMU consists of the three elementary stages like measurement stage, processing stage and communication stage. The pressure measurement achieved with Micro Electro Mechanical Systems (MEMS) sensor. The sensor output is converted to digital signal using ADC and fed to the microcontroller unit. The microcontroller unit is interfaced to the computer; by this the sensor details accessed from microcontroller unit are updated to PC using Visual Basic (VB). A regulator circuit removes the ripples and also remains the same dc value even if the input dc voltage varies, or the load connected to the output dc voltage changes. This voltage regulation is usually obtained using one of the popular voltage regulator IC units.
