Abstract：The combination of sensor and computer technology makes the measurement of various physical quantities easy, convenient and smart. In this article, a digital pressure gauge that is suitable for measuring liquid pressure is designed. The design of high precision digital pressure gauge uses pressure sensor as its foundation and uses ATmega16 as its controller.
Key words：microcontroller; accuracy; pressure gauge
