Carbon dioxide detector using Arduino (mini project)

CO2 is one of the greenhouse gas contributing to global warming. In this video, I will be making a CO2 detector using Arduino nano and MQ 135 gas sensor which can measure eCO2 or VOC. Components required: 1. Arduino nano ( any Arduino board ) 2. MQ 135 gas sensor 3. 16x2 LCD display 4. 220-ohm resistor 5. Buzzer ( optional ) In the video, I have explained how the connections are done and how to program Arduino to get the desired output. Follow the video to get more information. Code for the LCD display and the project is in the link below: ___________________________________________________________________________________________ drive.google.com/file/d/1dt-NEFX2EDdV3EP9Q47IujBRH… ___________________________________________________________________________________________ A special vote of thanks to the team BlackHawks I.e, Khaleel Ahmed Nisha Mujahid Mirji Keep supporting, stay tuned and hit that like button, subscribe.
