Overview

The Smoke Detector System using MQ135 and ATmega328 is a highly effective solution for detecting smoke and harmful gases, enhancing safety in residential, commercial, and industrial environments. This system integrates the MQ135 gas sensor with the ATmega328 microcontroller to provide accurate and reliable smoke detection.

Components

MQ135 Gas Sensor
The MQ135 gas sensor is designed to detect a range of gases, including smoke, carbon dioxide, ammonia, and benzene. It operates by measuring the concentration of these gases in the air. When smoke or gas levels exceed a predefined threshold, the sensor’s output signal changes, indicating a potential hazard.

ATmega328 Microcontroller
The ATmega328 microcontroller, commonly used in Arduino boards, serves as the central processing unit of the smoke detector system. It receives data from the MQ135 sensor and processes it to determine the presence of smoke or hazardous gases. The ATmega328 is known for its reliability and ease of use, making it an ideal choice for embedded applications.

Functionality

The Smoke Detector System operates by continuously monitoring the air quality through the MQ135 sensor. The sensor detects changes in gas concentration and converts this data into an electrical signal. The ATmega328 microcontroller processes these signals and compares them to predefined threshold values.

When the gas concentration exceeds the set threshold, indicating the presence of smoke or dangerous gases, the microcontroller activates an alarm or notification system. This can include audible alarms, visual indicators, or even sending alerts to a connected device. The system is designed to provide timely warnings to ensure prompt action and prevent potential hazards.

Benefits

This smoke detector system offers several advantages:

• Early Detection: The MQ135 sensor provides real-time monitoring of air quality, enabling early detection of smoke or harmful gases.
• Reliability: The ATmega328 microcontroller ensures accurate processing and reliable performance.
• Versatility: The system can be used in various settings, including homes, offices, and industrial sites.
• Safety: By providing timely alerts, the system enhances safety and helps prevent accidents related to smoke and gas exposure.

Overall, the Smoke Detector System using MQ135 and ATmega328 is a valuable tool for maintaining a safe environment by ensuring prompt detection and response to smoke and hazardous gases.
