09/03/2018· 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. My initial impressions of the module were pretty favourable.

17/07/2020· CO2 Sensor (MH-Z14A) An example for using MH-Z14A and Arduino Uno to detect CO2 level. It'll receive the result from MH-Z14A via pin 3,4 by UART communication and send the result via Hardware Serial (tx, rx) which is 0 and 1 in Arduino Uno.
20/07/2016· 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.
MH-Z14A Library. Sensors. A Library for using the MH-Z14A CO2-Sensor with Arduino. Offers all methods mentioned in datasheet and debug-log. Author: Jan-Niklas Bogatka. Maintainer: Jan-Niklas Bogatka.

27/04/2021· Using the UART interface of the MH-Z14A with an Arduino microcontroller (red line) Using the UART communication to receive the CO2 values from the MH-Z14A causes similar problems like the analog interface. We can see that the UART sensor values crack down and are running for time parallel to the PWM interface before they go up again. This behavior seems to be unregular and prevents the …

06/05/2021· I got the sensor but it is crap. PWM output doesn't work (it is either continously high or low instead of the PWM signal it should output.) and analog outputs are very inaccurate, reading starts high, over 500 ppm, sometimes more, then slowly goes down to ~280 ppm, where it stays.
