ESP8266 sensing CO2 + Temp + RH + Pressure - Atomstar's ...

· When connecting the serial MH-Z19B sensor to the ESP8266 board, you have two choices: Recommended: use software serial port (any pins, 12 and 13), lower baud rate, and keep logging ; Use hardware UART (pins RX and TX) and disable logging, see also this issue; Unfortunately it took me a while to figure out SW serial works, so several of my first boards (like the one below) use the hardware ...

· Measuring CO2 with MH-Z19B on ESP32 with MicroPython. In the previous posts, I described a simple weather station that measures temperature and humidity and sends the measurements to a Google sheet. The system is supposed to be used at home. Therefore, one of the next possible improvements can be measuring air quality in a room. That can be done, for example, by adding an MH-Z19B …

mh-z19 · PyPI

· Features about calibration (both MH-Z19 & MH-Z19B), detection range change (MH-Z19B) and ABC logic on/off(MH-Z19B) are implemented at version or later. I'm afraid I've just only implemented these without test due to lack necessary devices and apparatus for the test, fx: standard concentration CO2 gas, also MH-Z19B module. If you have these devices or apparatus and try to use …

CO2 meter using M5StickC -

· MicroPython: Story . Preface. Cause I've been working at home and being cooped up in my room, I decided to make a CO2 meter as a guide to ventilate my room. A MOX gas type that called CCS811 showed inappropriate results for measuring actual CO2 concentration, such as higher readings due to human farting, so I use a high-precision NDIR-type MH-Z19B in this case. I designed all of …

Tindie Blog | CO2 sensor

The MH-Z19B is a pretty neat sensor. It uses non-dispersive infrared to detect the concentration of CO2 in the air. This makes it pretty immune to the percentage of oxygen in the air, and with no moving parts or chemical sensor elements it should have a fairly long lifespan. It can detect concentrations up to 5000 ppm, at which point most humans are unable to focus well, complain of “stuffy ...
