Implementasion of Calibration in Gas Hazardous Carbon Monoxide, Carbon Dioxide and Methana in Closed Room Using Fuzzy Method

Abstract

The results of testing the system when the active sensor detects 0 ppm CO2 gaseous gas, 440 ppm CO2 and 0 ppm CH4 air condition "safe" with a not rotate exhaust fan output. In the active sensor, it detects CO 500 ppm gas, 410 ppm CO2 and 0 ppm CH4 "Danger" air condition with speed rotating exhaust fan output. While the active sensor detects CO 0 ppm gas, 308 ppm CO2 and 540 ppm CH4 "Very Danger" air condition with high exhaust fan spinning output. In conclusion, this study shows that the results of testing the system when the active sensor detects 0 ppm CO2 gaseous gas, 440 ppm CO2 and 0 ppm CH4 air condition "safe" with a not rotate exhaust fan output. In the active sensor, it detects CO 500 ppm gas, 410 ppm CO2 and 0 ppm CH4 "Danger" air condition with speed rotating exhaust fan output. While the active sensor detects CO 0 ppm gas, 308 ppm CO2 and 540 ppm CH4 "Very Danger" air condition with high exhaust fan spinning output.
