MH-Z19 PWM. The PWM output has a period of 1004ms. The amount of time that the signal is high corresponds linearly with the sensor's maximum ppm. Since timing the PWM output takes 1 second per reading, it may be desirable to just use the UART interface to poll the sensor. For the ESP8266, you can use this project to interface with both the UART and the PWM output: https:// ...
22/12/2019· The advantage is that you keep logging and uploading firmware over the serial (USB) port. When connecting the serial MH-Z19B sensor to the ESP8266 board, you have two choices: Recommended: use software serial port (any pins, 12 and 13), lower baud rate, and keep logging. Use hardware UART (pins RX and TX) and disable logging, see also this ...
