Design of a Calibrator for Methane Sensor Based on DSP

  • In allusion to problems of few calibration point, low accuracy and large volume of traditional calibrator for methane sensor, the paper proposed a design scheme of calibrator for methane sensor based on DSP and introduced hardware and software designs of the calibrator in details. The calibrator uses DSP chip TMS320LF2407 as main control chip, realizes simultaneous calibration of 8 methane sensors with accurate result, which greatly improves work efficiency and saves working time.
