Abstract：In recent years ,the multi parameter detect instrument has become the new trend of development ,which also can detect temperature and humidity index in coal mine underground at the same time .But because the detecting instrument is for special occasions ,and temperature and humidity index is changing ,the front end of gas sensor is easily affected by the temperature ,which leads to the decrease of the measurement accuracy .Therefore ,this paper studies a kind of temperature compensation algorithm in order to solve this problem ,and applies this algorithm to the realization of the algorithm based on the FPGA as the main chip .Finally ,this paper uses the simulation software fitting curve ,then comparative analysis before the algorithm of data and the after data to get the signal‐temperature curve ,which proves that the temperature compensation algorithm is correct and reasonable .
