The air in sucked into the air chamber where the gas sensors detect the parameters of the atmospheric air. The parameters are displayed on the Blynk-IOT app with the help of the data streams. The air is then filtered and then again, an MQ135 sensor measures its quality. The air is then sucked out of the air chamber. The voltmeter measures the voltage at all times so as to monitor the voltage. Thus, is to ensure that the voltage does not surpass the limit upto which the components can work efficiently.
