Pocket Size CO (carbon Monoxide) Detector



In this project we will be making a pocket sized CO detector which is used to detect Carbon monoxide in air our goal was to make this device portable and which fits in pocket size.
Now a days we are facing problem of air Pollution due to industrialization every day harmful gases are released into air and even vehicles releasing harmful Carbon monoxide.
So we thought of making this project which we could carry anywhere and check the air condition whether it is clean or polluted.
We have build this project in a affordable budget,it costed around 12 USD.Parts Used


Parts used
  • Arduino Pro Mini
  • Oled 128*96 Display
  • MQ9 Carbon Monoxide Sensor
