Abstract

The paper introduced calibration principle and functions of coal mine gas sensor and composition of automatic calibration device of gas sensor. It described design of hardware and software of data collection module of the automatic calibration device. The module solves the problem of data exchange between the automatic calibration device and the gas sensors which have same address of I2C bus, and it is simple and efficient and has low cost.
