“…The application of stand-off detection of alcohol in the air exhaled by humans may solve the problem. There are some articles describing stand-off detection of alcohol in moving cars [ 10 , 11 , 12 , 13 ], however its application to examine humans entering a specific area has not been described so far. In this article the theoretical analysis of such application as well as experimental results of the developed experimental setup are presented.…”

Early detection of humans under the influence of alcohol in public places (workplace, public gathering) is particularly important for safety reasons. In this article, the theoretical analysis of stand-off detection of alcohol in the air exhaled by humans as well as experimental results of the developed experimental setup is presented. The concept of differential absorption of two laser beams at different wavelengths was used. The idea of using standard deviation of the relative difference of the amplitudes of two signals to detect the alcohol was applied for the first time. The idea was verified by the experiments and it was shown that a reliable device can be developed that can efficiently detect alcohol concentration in the exhaled air at the level of 0.3 mg/L (0.63‰). Moreover, the concept of such device examining humans entering a specific area was proposed. The results of this article may be useful to scientists or engineers working on alcohol detection in human blood.

“…By adding the wireless to our implementation (though also mobile network like 3G-LTE could be an option [5]), data is transmitted in real time, captured and processed much faster, the measurement can be time-stamped, thus becoming evidence, data cannot be erased or modified. This kind of integrated communication uses a low-cost technology that can be implemented in any type of device and it provides flexibility and opens the borders in any area of interest.…”

As driving under the influence of alcohol is the main cause of fatal vehicle accidents, a reliable method for alcohol testing and data recording, without the possibility to fraud the system is mandatory. Thus, besides the alcohol level measurement, a communication method for remote recording of the test results should be provisioned. This paper describes a microcontroller based implementation with real-time transmission of data, retrieved, modeled and displayed in a chart format, and furthermore securely stored in a record database. In our demonstrator, the code for the microcontroller ATmega328p that controls the data acquisition and transmission is written in C++, while the application created in C# controls all the sensor received information for calibration, verification and metrology testing. The system implementation uses low cost components with high performance.
