Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

· The MH-Z19 sensor is manufactured by Winsen Lt., ... UART serial interface and Pulse Width Modulation (PWM) output. A nondispersive infrared sensor (or NDIR sensor) is a relatively simple spectroscopic sensor often used as a gas detector. It is nondispersive in the sense of optical dispersion since the infrared energy is allowed to pass through the atmospheric sampling chamber without ...

arduino - MH-Z19 CO2 sensor giving diferent values using ...

· I have a MH-Z19 CO2 sensor, according the data-sheet I can obtain PPM values via UART and PWM. The difference between both method is the limit in the CO2 concentration, where UART I should have readings between 0-5000ppm, and via PWM I should have readings between 0-2000ppm. I just wanted to know if I can have the same readings using both methods, but after tried I'm realized …

MH-Z14A CO2 Meter Tutorial with Arduino, ESP8266 or ESP32

· Using the PWM interface of the MH-Z14A with an Arduino microcontroller (green line) The PWM interface is the only one that has no outliers and can therefore be used for our CO2 alarm. Most of the time the PWM values are also validated by the CO2 concentration from the UART interface. Key findings using the Arduino with the MH-Z14A after the recalibration. Maybe you saw that the sensor …

Review and Test of the MH-Z14A NDIR CO2 Sensor

· 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.
