Design and Development of Real Time Indoor and Outdoor Air Quality Monitoring System Based on IoT Technology

While the countries grow to be developed and industrial, the pollution level is increased significantly, and this becomes a critical downfall for the people's health. This paper presents a system of smart air quality monitoring for urban city area by using IoT Technology. The main purpose of this research is to minimize, improvise, and use low-cost configuration, yet with equal ability to perform as industrial sensor capability, as required by the IEEE 1451 Sensor Standard. This enables the usage of this system in range of 20 meters for the WIFI module. This module consists of two sensors that function to detect concentrate elements in nearby environment. The first sensor is an air quality sensor that functions to detect the value of carbon dioxide in the environment. The second sensor detects and indicates the temperature and humidity. Both sensors will show the values detected through wireless monitor, either by smartphone or any device that can access web-based or application platforms. This is to ensure that the value is detected, hence ability to observe. Any malfunction can be reset remotely, and the user can determine the next decisions. The proposed system, by combination of esp32, IoT Platform and the Wi-Fi modules, is also able to give immediate data reading, while being remotely observed by notice from the system output.
