deolah Posted January 26, 2006 Report Share Posted January 26, 2006 Hi, My final year project is titled as above. i found out i would need a semiconductor alcohol sensor for this project. This as i found out, lcomes in form of chips. i really need to know which one to get for my project to work fine. the Breath alcohol tester is supposed to test the level of alcohol in the breath ( and also blood) of an intending driver. if the BAC is found too high, then it wont allow the car start. Am thinking there should be a relay connected to this device, then to a switch that will operate the car ignition system. Pls give me ideas of the type of semiconductor alcohol microchip sensor to use and how do i get it? do ui have to order for it from my country or i can easily access it? i also need to know the principle of operation of this sensor and howi can calibrate my device to measure different levels of alcohol content. Pls reply asap as my project initiation is dependent on this. thanks a lot. Quote Link to comment Share on other sites More sharing options...
privas Posted January 28, 2006 Report Share Posted January 28, 2006 I don't think anyone should be helping with this project. If you need an Breath Alcohol Tester in your car, it for a very good reason. Probably too many convictions for Driving Under the Influence of Controlled Substance AKA driving drunk.

MP Posted January 28, 2006 Report Share Posted January 28, 2006 privas,He is building one, not modifying one. It is a project.deolah,The only gas sensors I am familiar with are the Figaro ones. You can get data sheets and find distributors on their website at www.figarosensor.comHope this gets you started.MP Quote Link to comment Share on other sites More sharing options...
