Abstract
A vehicle air monitoring system includes a housing defining an interior and an inlet. An airflow assembly is disposed within the interior and includes a pump configured to draw an air sample into an airflow passage via the inlet. A detection assembly is in fluid communication with the airflow passage of the airflow assembly. The detection assembly includes a light source configured to illuminate a biochip and a photodetector configured to detect an optical transmission of the biochip based on a photocurrent of the photodetector. A control assembly is in communication with the airflow assembly and the detection assembly. The control assembly is configured to activate the pump to draw the air sample into the airflow passage, compare the photocurrent by the photodetector with a predefined baseline photocurrent to determine a change in the optical transmission of the biochip, and communicate particle data to a remote device.
