Introduction

As technology advances, the safety and comfort of the house become increasingly important. One innovative solution is to use the Internet of Things (IoT) to build early detection systems such as fires. This article will discuss the design of temperature and smoke detection devices with IoT based on the ATmega328P microcontroller, which is able to provide fast and effective warnings to homeowners via email.

Detection System Mechanism

The system uses two main sensors: gas sensor (MQ-2) to detect smoke and temperature sensor (DS18B20) to detect room temperature. The ATmega328P microcontroller acts as the system of the system, processes data from the two sensors and sends warnings via email.

Smoke Sensor (MQ-2)

This sensor works based on changes in resistance caused by the presence of smoke. When the concentration of smoke in the air reaches a certain level, the sensor will send a signal to the microcontroller. The MQ-2 sensor is a popular choice for smoke detection due to its high sensitivity and reliability.

Temperature Sensor (DS18B20)

This sensor measures room temperature and sends data to the microcontroller. The system is programmed to send a warning if the room temperature exceeds 23 °C. The DS18B20 sensor is a digital temperature sensor that provides accurate and reliable temperature readings.

Microcontroller ATmega328P

This microcontroller receives data from the sensor, processes it, and sends a warning message via email if needed. In addition, the microcontroller also controls the buzzer as a sign of danger. The ATmega328P microcontroller is a popular choice for IoT projects due to its low power consumption and high processing capabilities.

System Workflow

Smoke sensors and temperatures constantly monitor the condition of the room.
If the sensor detects the smoke or temperature exceeds the threshold limit, it will send a signal to the microcontroller.
Microcontroller processes data and sends warnings via email.
The system will also sound a buzzer to give a voice warning.

System Advantage

Early Detection

This system is able to detect fire hazards earlier, so as to provide sufficient time for residents to save themselves and contact help. Early detection is crucial in preventing fire-related injuries and fatalities.

Effective Warning

Vigorous via email allows homeowners to find out the danger situation, even if they are not at home. This feature provides an added layer of safety and security for homeowners who are away from their homes.

Easy to Implement

This system is designed to be easily installed and configured, so that it can be accessed by users with various levels of expertise. The system's user-friendly interface and simple setup process make it an ideal choice for homeowners who are not tech-savvy.

Solutions and Considerations

Internet Connection

This system requires a stable internet connection to send an email. A reliable internet connection is essential for the system to function properly.

Maintenance

Sensors must be regularly cleaned and checked to ensure optimal functions. Regular maintenance is crucial to ensure that the system continues to function properly and provides accurate readings.

Battery

The system requires battery resources to operate. Consider batteries with long and easy to replace life. The system's battery life should be sufficient to last for an extended period, reducing the need for frequent replacements.

Conclusion

Design of temperature and smoke detection devices with IoT based on ATmega328P microcontroller is an intelligent solution to improve home safety. This system provides early detection and effective warning, thus helping to protect residents and property from fire hazards. With the development of IoT technology that continues to increase, it is hoped that this system can continue to be improved and expanded to provide more comprehensive and sophisticated protection.

Future Work

Future work can focus on improving the system's accuracy and reliability. This can be achieved by using more advanced sensors and algorithms. Additionally, the system can be expanded to include other features such as motion detection and gas leak detection.

Limitations

The system has some limitations, including the need for a stable internet connection and regular maintenance. Additionally, the system's battery life may not be sufficient for extended periods of use.

Recommendations

Based on the system's design and functionality, the following recommendations can be made:

Use a more advanced sensor to improve the system's accuracy and reliability.
Implement a backup power source to ensure the system continues to function in the event of a power outage.
Consider using a more energy-efficient battery to reduce the system's power consumption.

By addressing these limitations and recommendations, the system can be further improved and expanded to provide more comprehensive and sophisticated protection for homeowners.
