The onboard smoke meter for heavy-duty diesel vehicles is a laser fiber optic sensor that uses light transmission method to detect the concentration of particulate matter in the exhaust of heavy-duty diesel vehicles.

When car exhaust passes through the detection chamber, the laser will be blocked, and the photoelectric or light detector will record this.

The optical signal is transmitted to the data analysis module through the optical fiber, and the data analysis module converts the optical signal into an electrical signal, and Real-time computing the concentration of exhaust particles in real time.
