Replaceable alcohol sensor module

摘要

A replaceable alcohol sensor module for use with a breathalyzer. The alcohol sensor module requiring calibration can be removed from the body of the breathalyzer and replaced with a new alcohol sensor module. The replaceable alcohol sensor module has at least an alcohol sensor and an adapter that removably connects the replaceable sensor module to the breathalyzer. The adapter transmits the electrical current generated by the alcohol sensor to a processor of the breathalyzer for processing. The alcohol sensor and the adapter are mounted on a printed circuit board to provide the replaceable sensor module.

1. A replaceable alcohol sensor module for use with a breathalyzer comprising:
an alcohol sensor that is calibrated to provide an electrical current proportional to an amount of alcohol detected in a breath sample; an adapter to removably connect the replaceable sensor module to the breathalyzer and to transmit the electrical current generated by the alcohol sensor to a processor of the breathalyzer for processing, the processor measures the electrical current and calculates a blood alcohol concentration of the breath sample based on the measured electrical current; a printed circuit board to mount the alcohol sensor and the adapter; and wherein the replaceable alcohol sensor module is installable in the breathalyzer to replace existing replaceable alcohol sensor module in the breathalyzer after being used for a predetermined number of times.
