Abstract

In bioethanol purification device, result of process has to measure the level of alcohol usually by alcohol meter or by picnometer but need more then 100ml sample and need much time to measure. The measuremet alcohol level by sensor detecting the vaporized alcohol in the air that will caught gas sensor TGS 2620. Therefore, development of simple and quick detection of alcohol level in purification result is strongly required. The alcohol equipment detection consists of a microcontroller module, a sensor module, output module and a bioethanol tube. There are two tubes that are used as a container for the bioethanol purification. The first container is automatic alcohol sensor tube, and the second container is storage tube for result bioethanol purification. Bioethanol data detection is displayed through the LCD and a computer. The microcontroller modul regulate the delay time, process sensing and display results. After alcohol levels are detected, then the alcohol sensor will be cleaned by blowing the fan so that the alcohol vapor attached will disappear. The delay time is set so that the sensor reading has an accurate value with the smallest error detection
