Open Source Project Arduino, IOT and Gas Sensors

This project aims at developing a system which can capture concentration of various gases in air and upload this information on a website on regular basis after a interval.

Real Time Air Quality monitoring with Arduino and IOT(ESP8266)

I am using four sensors for capturing gas concentration and with ESP8266 IOT interface i am accessing a webpage(#PHP), which in turn uploading this information to the database.

PHP page for monitoring

Before developing the hardware i tested all the code using an Arduino board and one hand made circuit of ESP8266 using zero pcb.

After testing the Gas sensors, IOT code along with PHP code, I designed the following pcb and developed the project completely.
