This work proposes an equipment oriented to measuring the alcoholic level and simultaneously applying face recognition for people who enter risk places where their physical integrity can be affected due to their drunkenness state. In the state of the art, it is verified that several alcohol measurement methods do not integrate the simultaneous facial recognition for the purposes of proper personnel access control and registration. It is also verified that these methods do not integrate a module for air flow detection that allows corroborating that the person is using the equipment. Finally, it is authenticated that subjective methods are applied such as the emitted smell perception, gait and way of speaking or behavioural aspects. The proposed equipment solves these deficiencies through sound, alcohol and image sensors connected to a single board computer; which allows the measurement of the alcoholic level through the breath and simultaneously applying facial recognition; as a consequence, it improves the operability and procedures in companies. Biometric face recognition is carried out through image processing algorithms, convolutional neural networks and support vector machines SVM, which run on a computer which is synchronized with the measurement equipment. The computer registers the recognized person in a database with the associated detected alcoholic level. For the validation of the proposed equipment, several samples of alcoholic level, airflow detection rate and face recognition rate were evaluated. Alcohol level measurements were compared with those obtained through a certified digital breathalyzer. In this validation, Pearson's correlation coefficient was used, obtaining a value of 0.937. The airflow detection success percentage is 91%, while the percentage of true face recognition was higher than 95%.
