Abstract:

Due to the increased emissions of hazardous gases from vehicles and industries, the density of polluted air increases in the surroundings.

It leads to human health problems such as asthma, lung disease, bronchitis and even premature death if the polluted air conditions are severe.

In addition, polluted air can cause global warming and acid rain that causes unhealthy crop growth and the pollution of water supply sources.

Therefore, a smart monitoring Robot system is essential to check the air quality.

This project proposes a device of air quality monitoring Robot to efficiently monitor air conditions in real-time and sending alert notifications via mobile Blynk application.
The device comprises ESP8266 module Node MCU board as microcontrollers, DHT11 temperature sensor and MQ-9 and MQ135 detection gasses sensors such as LPG, smoke, alcohol, propane, hydrogen, methane, and carbon monoxide.

The proposed system is designed with a user-friendly GUI mobile application and web based.

The monitoring results can be displayed in a mobile app with integrated real-time data transmitted by connecting to Wi-Fi network.

In this project, the Internet of Things (IoT) based in the air quality monitoring Robot plays an important part. Accordingly, the users can receive updates from the mobile apps at anytime and anywhere.

• Design, build, calibrate and test a low-cost portable air quality monitor
• Develop an Android app to collect data from the sensors and send it to the cloud
• Identify the limitations of this technology and areas for further advancement
• By using wifi controlling the robot
