Abstract

Driving vigilance is a pressing road safety issue that many people face in their daily lives. This project proposes to develop a low-cost sensing device that can help detect a driver's alcohol level. Alcohol is the world's most abused drug. Alcohol abuse affects more than 18.5 million adults in the US, with a loss of productivity, health, motor vehicle, criminal and other related costs in the company over USD 200 billion annually. The percentage of all hospital admission (> 20 percent) and death ~100,000 each year are due to alcohol-related diseases. This project's purpose is to develop a low-cost sensing device for alcohol sensors. The sensing system consists of Agarose Gel and HEC/PVDF as a coated material that are being optimized by applying 1 to 3-layer of coated to run the obtain the optimum voltage output. Those coated glass substrate will be kept dry for 24 hours before applying ethanol concentration on to the glass substrate to proceed the experiment. The data analysis that will be taken in this project is Optimization number of layers, Repeatability, Hysteresis, Stability and Time Response. In sum of, the best coated material will be taken for the proposed sensor. Arduino is used to obtain the output voltage for all the experiment
