12/02/2021· In the previous tutorial, we discovered and tested the MHZ19 sensor which allows to measure the CO2 concentration without calibration. We saw how to read the CO2 concentration returned on the sensor PWM pin in MicroPython and then publish it on a Domoticz server via the HTTP / JSON interface. In this new tutorial, I propose to do the same thing with Arduino code. The code is …
21/09/2015· MHZ16 sensor has a UART interface, and with the help of the adapter(I2C to UART bridge IC SC16IS750) user could connect this sensor to an I2C interface to save two IO pins. MHZ16 has a feature called “auto self calibration”, which is an algorithm builtin the firmware of the sensor. The SIMPLIFIED working principle of this algorithm is something like this: 1. The sensor keeps tracking ...

31/07/2019· Each dev board is different. I suggest you look for an eschematic for that particular one, or use a multimeter to check where those pins are connected. Later you can use the ESP32 module datasheet to check what pin number it is. BTW, if I am not mistaken, you can route UART2 pins (TX2RX2) to any gpio pin of the ESP32 you want, in code. Top.

12/06/2021· I successfully tested it with an MHZ14 and an MHZ19C. However, you must make sure that the measuring range you have selected can actually be set. You will see that a measuring range has not been set if the values you receive via PWM and the serial query are significantly different. And – as already mentioned – not all commands work with every model.
