Air pollution has an effect on our everyday lives. It poses threats to the world's biodiversity and quality of life. Due to the rapid increase in industrial activity over the years, there is a much greater need for monitoring the air quality. This project proposes a framework for tracking air pollution. The proposed model is regulated by an Arduino mini control. Air pollution observance system is intended to trace and evaluate air quality in real time with the knowledge retrieved from an overseas server and saved online. Measurements of air quality depend on the components, which are measured in terms of Million Metrics (PPM) and analyzed in Microsoft Excel. The air quality measurements taken by the established system were also precise.

To ensure proper hygiene and safe food quantity and quality, food quantity and quality should be examined and monitored on a regular basis. Some businesses can add adulterants to food products to satiate the thirst of selfishness, and make a lot of money by selling low-quality food at a higher price. Since human health cannot be compromised, a food adulteration monitoring system should be established to detect the presence of adulterants in food products. The proposed method is governed by Arduino, which regulates the use of sensors within the system. The recorded information will be transferred to the LCD digital display, which includes alphanumeric display module and therefore the result is displayed. With the employment of this technique, the consumption of poor-quality food will be avoided. Mostly, the simplicity of the system will facilitate everyone (consumers, food inspectors, etc.) to use the food adulteration observance system.
