Described is an electronic device for selling information about the levels of ethanol (alcohol) in the exhaled air and blood, operated by coins, which has an oxide semiconductor sensor, highly sensitive to ethanol, for performing tests of alcohol concentration in breath and blood (in BAC,AMERICAN BAC OR BRAC system). The electronic device contains visual and hearing indicators which assist the user all the time. The electronic device comprises microswitches in the electronic processor thereof for a total programmability of operations, thus providing different options (language, number of coins, type of analysis and representation of the same, measurement limits, coin counter, etc). The device provides the results in a reliable manner since it has a temperature stability control integral with the sensor, also controlling the insertion of coins and a safe data retention.
