Publish the CO2 concentration of an MH-Z19 sensor to ...

Feb 12, 2021· Presentation of the CO2 sensor MH-Z19. The MH-Z19 is a self-calibrated sensor, ie the measurement sent by the sensor does not require any mathematical treatment. In other words, the CO2 content expressed in ppm (parts per million) is recovered. The MH-Z19 has a PWM output and a UART digital interface (serial port).
