Review and Test of the MH-Z14A NDIR CO2 Sensor

Mar 09, 2018· Review and Test of the MH-Z14A NDIR CO2 Sensor. The MH-Z14A measures CO2 concentrations using absorption of infra-red light. These devices are available on eBay, Amazon and other places from about $20. Ignore the capacitor across the power pins - this was a failed attempt by me to improve the reliability of the analog outputs.

Jul 20, 2016· Re: MH-Z14A CO2 sensor. I need to use this sensor but there is very little documentation on the flying lead header pitch. i need to use a connector that will securely fit the flying wire off of the sensor board to my PCB. but i don't know the pitch it is using, from pictures it looks like either the pitch or pitch.

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

Mar 10, 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 ...
