Abstract: At present, a lot of mine-used sensors are given priority to with LED digital tube display, which does not fit the needs of multi-parameter sensor display. To solve the problem of display, using a customized LCD display as mine multi-parameter sensor display unit, the paper carried out the research and design for the sensor, and described the LCD screen hardware circuit and its control programming. The high definition of color LCD screen shows that the content is more abundant and has been well applied in the coal mine.
