by ADMIN 93 views

Introduction

Air health and cleanliness is the right of every individual. Unfortunately, cigarette smoke is one of the main causes of air pollution that can endanger health, both for active smokers and passive smokers. With cigarettes becoming one of the common addictive substances, its widespread use demands serious attention from various parties. It is estimated that in 2030, around 10 million people worldwide will die from cigarette-related diseases, and developing countries are predicted to contribute 70% of that number. In Indonesia, statistics show that 69% of men smoke, making it one of the countries with the highest smoking rate in Asia. Considering the fact that almost 70% of Indonesian smokers began to smoke before the age of 19 years, efforts to protect health are very necessary.

The Importance of Smoke-Free Policy

In this context, the University of Indonesia campus has launched a smoke-free policy since 2012, followed by other campuses such as ITS and Andalas University. Likewise with regulations at the regional government level, such as Perda Number 12 of 2009 concerning Non-Smoking Areas (KTR) implemented in Bogor City. Following these efforts, Al-Qur'an Science University is also committed to implementing KTR to create a healthier environment. The implementation of smoke-free policy is a crucial step in reducing the risks associated with cigarette smoke, and it is essential to have a reliable tool to detect cigarette smoke in smoke-free rooms.

MQ2 Sensor-Based Smoke Detection Tool

To support efforts to create a smoke-free room, it takes an innovation that can detect cigarette smoke effectively. One promising solution is the use of MQ2 sensors integrated with Arduino Uno. This tool can detect the presence of cigarette smoke in the air and give a warning to its inhabitants. The MQ2 sensor is a tool that is able to detect various types of gas, including cigarette smoke. This tool works by utilizing the working principle of a gas sensor that can measure gas concentration in the air. Arduino Uno, as the brain of this system, allows programming and sensor settings to operate as needed.

How MQ2 Sensor Works

The MQ2 sensor works by detecting the changes in the electrical resistance of the sensor material when it comes into contact with different gases. The sensor material is a type of metal oxide that changes its electrical resistance when it reacts with different gases. When the sensor is exposed to cigarette smoke, the metal oxide material reacts with the gas and changes its electrical resistance. This change in electrical resistance is then detected by the Arduino Uno, which sends a signal to the user indicating the presence of cigarette smoke.

Application of MQ2 Sensor-Based Smoke Detection Tool

The application of this technology is not only limited to the campus environment, but can also be applied in various other public areas such as offices, restaurants, and other public places. With this tool, space managers can more easily supervise and maintain air quality, thus creating a healthier environment for everyone. The existence of this MQ2 cigarette smoke-based smoke detection tool is certainly in line with the KTR policy which aims to protect the public from the dangers of cigarette smoke.
