MH-Z19 WEMOS D1

François GUILLIER's blog - Arduino

Between the screen, MH-Z19 and the Wifi, it is probably around 200mA anyway. The USB port of the Wemos D1 mini is plugged directly on a small power adapter. The usb cable can also be used to upgrade the firmware as no OTA was implemented on this project.

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

Feb 12, 2021· 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). For this tutorial, we will already start by exploiting the PWM output.
