MHZ14A Arduino Code | NDIR Co2 Sensor | Infrared Carbon ...

MHZ14A is an Infrared Carbon Dioxide Sensor for accurate NDIR (nondispersive infrared) Co2 measurement using Arduino, STM32, Raspberry Pi. This NDIR Co2 sensor is a small size, common type sensor, NDIR principle to sense the presence of CO2 gas in the air. This NDIR Co2 sensor provides good selectivity, long life and nonoxygen dependent.


CO2 Monitoring with K30 Sensor Arduino Project Hub

I tried a number of analog CO2 sensors for that project, but I ran into calibration issues until I got a K30 CO2 module. This is a NDIR, digital, autocalibrating sensor, so it''s pretty easy to use. I am now starting a new open source project, this time using Arduino. I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino.

MQ2 Reading different gases Sensors Arduino Forum

20210506· Using Arduino. Sensors. louisbourdon August 8, 2013, 7:14pm 1. Hi all. I am using this code example from Sandbox Electronics to read from the MQ2 gas sensor. However, all my readings are 0. If I use a simple analog reading on the specific pin, I get the expected analog values from 0 to 1023, usual values around 250, and if I expose it to gas for example goes up to 1000. The reason I want to ...
