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.
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.
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.
You can find the complete project with illustration on my website
