Popis:	DOI: 10.14684/intertech.13.2014.452-456 On a breathalyzer measures the amount of alcohol per liter of alveolar air, ie air from the lungs. The project aims at the development of a breathalyzer, using the sensor of gas MQ-3, a drive microcontroller Arduino Uno and a liquid crystal display. For each concentration of sensor alcohol determines a value displayed on the serial port 'COM3' Arduino Uno with a range from 0 to 1023, this variation corresponds to the output voltage, ranging from 0 to 5 volts of the circuit for each concentration. The concentration is measured appears on the LCD, determining the concentration present in the air. Index Terms — Bafometro, Sensor MQ-3.
