Abstract :
This paper investigates the sensing characteristics of the gas sensor. When Gas Sensor is subjected to ethanol gas, the corresponding analog voltage output is obtained. This analog voltage output is proportional to the concentration of the ethanol gas in the vicinity of the sensor. In order to enhance the accuracy of sensing, various analysis such as range analysis, orientation analysis and concentration analysis are performed. Based on the experimental results obtained, the optimal values for sensing in real time is determined. Further the response and recovery time of gas sensing characteristics is also measured to validate the usage of gas sensor in multi-sensing scenario.
