Fix footprint for DC-DC module. Fix drill hole size for MH-Z19 footprint. As of this point the revision has not been produced as physical PCBs yet, though as they are based on the functioning first revision, it should just Work Fine (tm). The Gerbers themselves are released as open source hardware (OSHW).

MH-Z19 CO2 Sensor - Home Assistant

MH-Z19 CO2 Sensor. The MH-Z19 is a small non-dispersive infrared sensor that can measure CO2 level. High CO2 levels can lead to drowsiness, poor concentration, loss of attention or increased heart rate. The CO2 level outside is around 400ppm, but inside levels can reach between 1000 and 5000 ppm. High CO2 levels indicate that you should ...

Cannot get MH-Z19B CO2 Sensor to Work - Programming ...

May 06, 2021· Hi there everyone, I’m new this this forum and fairly new to Arduino. I’m having and issue getting my MH-Z19B CO2 sensor to read in my serial monitor. I’ve tried looking at many different examples of code that others have posted in their success stories. When I open my serial monitor, all I see is that the sensor is preheating. Nothing after that. The sensor needs about 3 minutes to heat ...

MH-Z14 and MH-Z19 CO2 Sensors • Wolles Elektronikkiste

Jun 12, 2021· The MH-Z19 library by Jonathan Dempsey is, as the name suggests, written specifically for the MH-Z19 sensors. It works with both the B and C variants. My attempt to use it for the MH-Z14 failed. The MH-Z19 library is characterized by the fact that it uses many of the undocumented commands, such as the query of the range or the firmware version.
