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 ...

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

27/04/2021· 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 …

arduino uno - Ethernet Shield - Not Working Properly Always - Arduino …

I'm working on a school project and using Arduino Uno. The basic working method for the project is as follows: Read temperature from LM-35. Read CO2 level in air using MH-Z14A. Upload data to server via an HTTP request. Now each piece of functionality above works fine when tested alone (If I only read temp it reads correctly. If I send data to database it gets sent correctly.) But when reading values and trying …
