The main aim of this project is to use a device that helps spread awareness to the user about the heaps of pollution spread by him/her. If this device is regularly well used, it can seriously bring down air pollution. First, the carbon dioxide sensor located at the bottom of the exhaust collects and analyzes the data. Then it is analyzed and calculated. From there, the data is transferred to the speedometer, where it is displayed as numeral form and classified as high or low. It constantly beeps to alert the user about his adverse affect on the environment. Added to that, the user can calculate his average throughout the drive using the mobile phone app.
