A Method for Improving Detection of Gas Concentrations Using Quadrotor
The work presents a solution to measure gas concentration with a special device and a wireless transmission module when gas sensors are attached on a mobile or flight vehicle.The device is designed to be a minor self-sealing air chamber with an ethanol sensor in it.It is a prototype to obtain the measurement more accurately and make sure minimum air turbulence effects,since the gas including the contaminants can fluctuate in the open air: The prototype provides ideas and methods for gas concentration measurement in a real environment.Its structure can also be modified into a smaller one.Design details have been discussed and this device was set under cross wind where it could be especially influenced by high-speed rotation from propellers.The assumption of security testing in different scenarios of different gas concentrations applying this fairly tiny size of this model,simplicity but precision of the chambers,is confirmed.Moreover,the temperature and humidity part are also collected and calculated to revise gas sensors data regarding the simulation effect of altitudes where the quadrotor would be.Experimental results show that this improvement of gas concentration detection can also be effectively applied in any hazardous environment using quadrotor or mobile vehicles where human cannot easily approach,such as factory chimneys,landfills,fire scenes,coal mine surveillance and so on.
