 ABSTRACT
 
 Alcohol is the common name for organic compounds that have a hydroxyl group attached to carbon and hydrogen atoms. The alcohol that is commonly found in liquor is ethyl alcohol or it is also called ethanol, but it is usually referred to as alcohol alone. Drinks with an alcohol content of 40% can lose consciousness, leading to accidents for alcohol-affected drivers. To detect alcohol in the body using an alcohol tester. Researchers tried to make a measuring instrument for alcohol levels in the body using several components such as Arduino nano, MQ 3 sensor, OLED, charger module, battery, resistor, push button, and buzzer. The design of a portable alcohol level detector through breath can work well, namely the results of the reading of alcohol levels in the body by the MQ-3 sensor through the breath and displayed on the Oled Display in units of% BAC (Blood Alcohol Concentration), in the sample comparison of the alcohol level reading between Final project tool with a comparison tool alcohol tester obtained the percentage difference in an average of 0.01% BAC.

Gelang Bel Rumah Untuk Penyandang Tunarungu Menggunakan Modul Rf 433mhz

“…Alat bantu ini menggunakan Aurduino Nano sebagai mikrokontroler untuk memproses suatu perintah [10]. Batasan populasi penelitian ini adalah penyandang tunarungu yang memiliki kemampuan motorik untuk memakai dan menggunakan gelang bel rumah [11]. Penelitian ini dapat memberikan pengalaman dan pengetahuan baru bagi peneliti dalam merancang, mengimplementasikan, dan menguji gelang bel rumah untuk penyandang tunarungu menggunakan modul RF 433MHz [12].…”

Design And Development Of A Portable Alcohol Testing Device For Motorists

“…This can reduce the risk of traffic accidents caused by alcohol-consumed drivers. Furthermore, the portable alcohol testing device can also serve as an effective tool in enforcing laws related to driving under the influence of alcohol.Previous related research has been conducted, such as the design of an alcohol breath detector using Arduino Nano [4]. This study utilized an MQ-3 alcohol sensor in the design of a similar device.…”
