Abstract: Taking PIC16F877 single-chip microcomputer as core and by use of its characteristics of more modules of its integrated peripheral equipment, a mine-used integrated sensor which integrated several kinds of sensor together was designed, the hardware structure and software programming of the sensor was introduced. The reliability of the sensor was improved with algorithm of 2 grades of data fusion.The integrated sensor is simple in programming and easy in use. It can be configured with different communication interface to meet demands of measurement and control network of enterprises.
