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 ...

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

11/07/2017· 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 deformation. Principle of operation: The main components …
