Abstract: In order to fully meet the majority of displacement detection applications and liberate human labor from the repeated displacement detection of various simple machines, this paper designs a high-precision displacement automatic tester. The tester uses STM32F103 series chip as the main control chip, uses stepping motor and high-precision grating sensor to design related hardware circuit, which has the functions of key control and LCD display. The tester designed in this paper has the advantages of simple circuit, reliable performance, convenient operation and high detection accuracy, which can well meet various displacement automatic detection applications. The test results show that the tester can meet the requirements of precision detection of digital display capacitive grid components, and has higher detection efficiency than traditional manual detection.
