How do we need to test it? Carbon monoxide is produced in incomplete combustion and thick smoke. We can place it close to cigarettes or paper that produces thick smoke from burning. The concentration of CO will change and be displayed on the screen. Do not test at the exhaust port or ventilation area of the car. Low CO concentration will not trigger the sensor to work, and the larger particles in the car exhaust will damage the accuracy of the sensor.
