Abstract
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 alcohol sensor module has at least an alcohol sensor and a circuitry mounted on a PCB that removable connects the replaceable alcohol sensor module to the breathalyzer. The circuitry transmits the signal and/or electrical current generated by the alcohol sensor to a processing unit of the breathalyzer for processing.

1-22. (canceled)
A replaceable alcohol sensor module, comprising:
- a printed circuit board (PCB);
- an alcohol sensor configured to receive a breath air sample and to measure blood alcohol concentration (BAC) based on analysis of the breath air sample;
- and
- a circuitry mounted on the PCB and configured to transmit measured BAC from the alcohol sensor to a signal processing unit of a breathalyzer;
- and
- wherein the pre-calibrated replaceable alcohol sensor module is installable in the breathalyzer to replace an existing pre-calibrated replaceable alcohol sensor module in the breathalyzer after being used for a predetermined number of times.
A breathalyzer, comprising:
- a signal processing unit;
- a replaceable alcohol sensor module comprising:
- a printed circuit board (PCB);
- an alcohol sensor configured to receive a breath air sample and to measure blood alcohol concentration (BAC) based on analysis of the breath air sample;
- and
- a circuitry mounted on the PCB and configured to transmit measured BAC from the alcohol sensor to the signal processing unit of the breathalyzer;
- an interface to connect the pre-calibrated replaceable alcohol sensor module to the signal processing unit;
- a display to display the measurement of the breath air sample from the signal processing unit of the breathalyzer to a user;
- and
- wherein the pre-calibrated replaceable alcohol sensor module is replaceable with another pre-calibrated replaceable alcohol sensor module after being used for a predetermined number of times.
A method of maintaining a breathalyzer having a pre-calibrated replaceable alcohol sensor module in a calibrated state, comprising the steps of:
- determining if the pre-calibrated replaceable alcohol sensor module requires calibration, the replaceable alcohol sensor module comprising:
- a printed circuit board (PCB);
- an alcohol sensor configured to receive a breath air sample and to measure blood alcohol concentration (BAC) based on analysis of the breath air sample;
- and
- a circuitry mounted on the PCB and configured to transmit measured BAC from the alcohol sensor to a signal processing unit of the breathalyzer;
- and
- replacing the pre-calibrated replaceable alcohol sensor module with another pre-calibrated replaceable breath alcohol sensor module after being used for a predetermined number of times.
