quality monitoring was evolved to observe the data and be vigilant users. Air quality can be scrutinized together with the web server and with linked smart devices via the application. Monitoring of air quality is effortless and competent using the Blynk App as it provides admittance anytime using smart devices. For IoT enabled system, the user obtains a notice through the Blynk Application on the mobile phone about the detection level of CO, NOx, RSPM, humidity and temperature for the area where the sensor nodes were deployed. An experimental set up for the IoT testing of air quality shown in **Figure 25**.

In **Figure 26**, the Blynk application on a mobile phone shows humidity as 20.9%, temperature as 34.17°C, CO as 44 ppm, NOx as 22 ppm and RSPM as 512 μg/m3 .

These real-time values are sent to the app using internet. A warning is sent to the App for alerting the user that the contamination in air is beyond which can be detrimental for human health. Alerting the users is mandatory to avert an environmental impairment and users can take instantaneously remedial measures.
