Pressure detection or control is an essential condition to ensure production and the equipment to safely operating, which is of great significance. The single-chip is infiltrating into all fields of our lives, so it is very difficult to find the area in which there is no traces of single-chip microcomputer. In this graduation design, primarily through by using single-chip and dedicated chip, handling of analog signal measured by the sensor to complete intelligent function. This design illustrates external hardware circuit design of intelligent pressure sensor, and conduct software development to the hardware.The design is based on measurement and display of STC89C52 single-chip. This is the p...
