We put together a gas sensor using a LCD display. The gas sensor measures the methane in the air. We have it set up so that the LCD display shows the amount of methane in the air as well as a text description saying whether the gas level is high or low. This is just a simple prototype for a bigger idea. This gas sensor unit would be attached to a drone, this drone would then fly through cities recording data of gas levels at specific locations. Using the data we can map out the air in a visual display to better understand our air quality and how it flows around us.
