ESP32-WROOM-32, CO2 sensor (MH-Z19C) and LCD

I'm Japanese. A reminder to remember what I've done. I'm blogging in the hope that it will be helpful to others who want to do similar things. I mainly write blogs about LEGO, AWS (Amazon Web Services), WordPress, Deep Learning and Raspberry Pi. At work, I'm working on installing collaborative robots and IoT in factories. I passed the JDLA (Japan Deep Learning Association) Deep Learning for GENERAL in July 2019. If you have any questions, please leave them in the comments at the bottom of the article.

    Hi, do you know if the sensor keeps not using auto calibration if you disable it via uart, also if you use pwm later?
    Picked up one of these sensors and reading up on howto use it.

      Thank you for your comment.
      Sorry, I do not know the answer to that question.
      I am using it with auto-calibration turned on.
      However, the manual seems to indicate that you can turn off auto-calibration and use it later with PWM.
