ABSTRACT:
A chemical vapor sensor system and method are provided, wherein the system includes an air input device, a light source, a detector, a sample chamber, and a processor. The air input device includes at least a sample input port, a reference input port, and an output port. The light source emits light, and the detector receives at least a portion of the emitted light. The sample chamber is in fluid communication with the output port, wherein the air alternatively enters the air input device from the sample input port and the reference input port and enters the sample chamber. The processor receives an output signal from the detector based upon a detection of at least carbon dioxide and ethanol in the air in the sample chamber, wherein the processor determines a blood alcohol content of a person whose breath was received in the sample input port.
