IOT ENABLED PORTABLE INDOOR AIR QUALITY METER AND POLLUTION DETECTOR SYSTEM

This system is able to calculate air quality inside and outside the vehicle. Helping/customers know when their in-vehicle air quality is good. This means purified air and peace of mind for drive and passenger alike. The architecture of Air Quality system using Raspberry Pi4 interfacing with different sensors and collected information of sensor uploaded into cloud. Recent trend is Internet of Things (IoT) technology and it is a popular worldwide system. Present days in Industries, Home Automation, Agriculture systems, Security systems and Drowns also uses IoT technology of “smart devices”. Sensors are collected information and connect with atmosphere parameters and interact with client and other systems. In this proposed model, several sensors are connected through an embedded system that collects data from the surrounding locations. In the current model, Arduino Uno, Raspberry Pi4 micro-controller plays an important role, to which various sensors like CCS811 CO2 Air Quality Sensor, DHT 11 Temperature and Humidity Sensor, Grove - Air Quality Sensor v1.3 are connected. The sensors are detected the level of carbon dioxide, carbon monoxide, temperature, humidity and dust particles present in the environment. Further, the sensor data are stored on a local server and excavated whenever necessary. Moreover, Python codes for different mathematical formulae are written which are used in the ThingSpeak. Finally, by the ThingSpeak, the various results are extracted and analyzed to check the environment condition.
