Publish the CO2 concentration of an MHZ19 sensor to ...

12/02/2021· The MHZ19 is a selfcalibrated 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 MHZ19 has a PWM output and a UART digital interface (serial port). For this tutorial, we will already start by exploiting the PWM output. Measuring range: 0 – 5000ppm: Precision: ± ...
