The Design of the Explosive Gas Monitoring Based on the SPCE061A

Abstract: An equipment which can detect natural gas,coal gas,hydrogen ,smoke and other easily combustible gas has been designed in this paper.The device based on a single-chip SPCE061A with voice processing functions,it can warm people when detected the harmful gases exceeding to the ordinary concontration value and implement the goal to detect and rapidly harmful gases in the air and give people a warning voice.The entire circuit is made up of detection circuit,SPCE061A single-chip microcomputer and peripheral circuit,power,voice output and several other parts.The single-chip controls the voice to draw attention of people to prevent while harmful gases detected.The instrument has many advantages such as high sensitivity,good stability,low cost,small power consumption,simple operation and so on.It can be used in chemical plants,gas stations,coal mine and other hazardous job places.
