Arduino Air Sensor : 4 Steps - Instructables

To add the Co2 sensor we need to connect to pin 6 on the MH-Z14 sensor. In my case i got a board on top of the sensor but I don't think this affects the working of the sensor. This board does come with a cable and connector. However the data cable coming from it is not the one i want to use. I fixed this by rerouting a extra cable to the correct pin. This pin needs to be connected to pin D3 on the Arduino.

arduino - How to use an MH-Z14a CO2 sensor? - Stack Overflow

10/03/2021· I have to use an MH-Z14a sensor, I've tried a lot of solutions but none of them work. I ended up with wiring the PWM to the digital 2 of my Arduino Mega2560, the V+ on 5V or (non of them give something working) and V- to GND, and I tried this code: // set interrupt pin numbers to recive outhput signal: const int sensorPin = 2; // Pin 2 as ...
