Our HUB contains ESP8266 Node MCU and 16 analog Multiplexer which allows us to connect our 16 modules to our main HUB.
Each Module is connected via a USB port and the user can put it in by their own choice.
On top of the HUB there is a power chord which will power our whole Device. We require Wi-Fi to establish connection with Our device and smartphone
FIG2: It represents our Block Diagram, that power flows from the HUB to the modules and all the information that the modules receive is sent to our Smartphones via Cloud. As a result, we get a display of the Air Quality in our smart phones
FIG3: It shows our module which is used to sense our atmospheric gases. It contains a USB port which can be put into our HUB.

FIG4: It displays our mobile application, pins, notification setup, email setup and module data.
