When drivers are waiting for the traffic lights, they usually dont stall cars, and then the tail gas will keep running all the time. Air pollution deteriorates with the growing number of cars. we designed a carbon dioxide testing machine. It can test the amount of carbon dioxide through the change of plant enzymes inside and give some prompt. The principle is that the plant carbonic anhydrase and the carbon dioxide will take a chemical reaction when they meet. The change will be recorded and the data will be processed and will exhibit on the LED screen, and then the driver will get the massage and cut off the energy.
