Abstract [en]

With the development of economy, more and more cars appear in the roads. Many drivers ignore thedanger about driving after drinking so that drunk driving causes a large number of traffic accidents allaround the world. By now, alcohol has killed a lot of people in the world. To reduce accidents causedby drunk driving, make certain the alcohol content in driver's body would help a lot, and it is related toalcohol concentration measuring and relevant instrument.In this thesis work, the design of a simple alcohol meter was present. The designed system iscomposed of a gas sensor (TGS-822) working circuit, microcontroller PIC16F690 and LCD display.The system collects the electronic signals caused by resistance changes in gas sensor (TGS-822) froma built-in Analog-to-Digital Converter (A/D) in microcontroller PIC16F690, programs withPIC16F690, and displays alcohol concentration in LCD display finally. The measuring concentrationrange of the designed alcohol meter is from 50PPM to 5000PPM. This paper describes the datacollection, processing and display of the designed alcohol meter in detail. And lastly, the authordiscussed about the advantages and disadvantages of the designed alcohol meter, it could beconsidered as a guideline for further work.
