This is to design and creatd. The system is created using Microcontroller in the family MCS-51 No.80C31 to control the evaluation to be brought to co-operate with the cycle of the gas sensor system. Quantity of gas, will be measured using a monitoring circuit the gas concentration will directing related to the sensor resistance. The analog signal related to the resistance will be converted into the digital sign. We use the microcontroller to reccive datas then used to analize the type of this gas.
