Making Alcohol Level Measuring Devices in Drinks Using TGS822 Sensors Based on AVR ATMEGA8535 Microcontroller

Introduction

In Indonesia, alcohol has become an integral part of the country's culture, although excessive consumption often occurs. Therefore, a tool is needed that can measure alcohol levels quickly and accurately. One suitable solution is the AVR ATmega8535 AVR Microcontroller alcoholic level that utilizes the TGS822 sensor. This tool functions by changing the analog data from the TGS822 sensor to digital data, which is then sent to the ATmega8535 microcontroller and displayed through the LCD (Liquid Crystal Display) M1632 screen. The program for the microcontroller is written using a basic language known as Bascom-AAVR.

How it Works: Measuring Alcohol Content

The TGS822 sensor operates with several important parameters, such as VC = 5 V DC, VH = 5 V DC, and RL = 1 K Ohm. This sensor produces varying DC voltage output according to the concentration of alcohol vapor around the sensor. This output value will be connected to the ADC (Analog to Digital Converter) input on the microcontroller, which is then displayed on the LCD. The data collection process is carried out at a certain time interval, which is 30, 60, 90, and 120 seconds. Before taking data, the sensor must be heated first for about one minute in order to provide accurate results. After heating, the microcontroller will process 20 ADC values displayed on the LCD. This is important to ensure that the measurements taken are representative and not the result of random fluctuations.

The Importance of Calibration and Accuracy

The output of the sensor is not always consistent, so in each measurement, data is needed for 60 seconds to be used as a reference. This process is important so that the measurement results are more reliable. Proper calibration and careful monitoring of environmental conditions are also needed, because factors such as temperature and humidity can affect the accuracy of measurement results. It is essential to note that the accuracy of the measurement results depends on the quality of the sensor and the microcontroller used. Therefore, it is crucial to choose a high-quality sensor and microcontroller to ensure accurate results.

Added Value and Benefits

This alcohol content measuring device has many benefits, especially for those who work in the beverage and health industry, as well as for personal purposes. With this tool, users can find out the alcohol content in drinks in real-time, which is very important to avoid excessive consumption that can be bad for health. In addition, with a system based on a microcontroller and modern sensor, this tool offers a more efficient and economical solution in measuring alcohol content. The device can also be used to monitor the alcohol content in various types of drinks, such as beer, wine, and spirits.
