Breath analyzer for use in automobile ignition locking systems
A breath analyzing apparatus for use in an automobile ignition locking system is described here.The present invention relates generally to breath analyzing devices and more specifically to an improved breath analyzing device used in an automobile ignition lock system which prevents a car from starting when the driver is intoxicated and which requires periodic rolling retests while the car is being operated. A breath sample tube receives a breath sample from a user. an air flow restrictor divides this tube into a high pressure section and a low pressure section. when a user is blowing into the breath analyzing apparatus, A pressure sensor is connected to the high pressure section determines it. A temperature sensor measures the temperature of the breath sample making sure that it is of the same temperature as of human breath. the breath sample is pumped into into a fuel cell by a micropump which is used to determine the alcohol content. Control means converts the output of the fuel cell into a reading which represents the breath alcohol content of the breath sample. when the ambient temperature drops below a specified level, the Heating elements warm the fuel cell. A housing holds all the major components of the breath analyzing apparatus and contains a tamper switch therein which detects when the case is opened.the alcohol content of the breath sample and the instructions and messages for the user is indicated by a display. The breath analyzing device is combined with an ignition locking system which disables the starting mechanisms of the car unless a satisfactory sample is blown into the breath analyzer device.There is also a means for for storing all of the data associated with the number, the time and the results of the tests. periodic rolling retests is conducted. Indications like warning response occurs such as flashing lights, activating the vehicle's horn or both if the driver fails the test.

This thread has the details of a microcontroller based breath analyser:
https://seminarproject.net/Thread-a-devi...4#pid17554 you can use it to implement the alcohol detector and then link it to the car ignition system.
