hi,
I ravikiran dodamani, presently in final year of engg in electronics and comm. Our group is performing project on alcohol detection and ignition locking in automobiles, we scanned though your post. We are almost done with our project but facing problem i.e we want to detect alcohol consumption while driving a vehicle , so we are using gas sensors. But the problem is, if the person sitting beside driver is drunk then also car stops and one more sensor is there called pulse sensor but the problem with that is we are getting only impaired device. This has to be attached to a person while driving. so can u plz suggest any idea or some sensors which over come our problem.
Kindly help us , we will be waiting for your reply.
