My project deals with the enviroCar Android application. The application connects with your car through an OBD bluetooth adapter and measures CO2 emission, fuel consumption, engine load and several other parameters. The parameters, such as CO2 emission and speed, are plotted in a chart against all the users who also use the enviroCar application. This helps to decide how ‘sustainable’ a driver you are (as shown in the image below). The data collected for a city can be used for showing CO2 hot spots in that city.
