MH-Z19B NDIR CO2 Module 1. Profile MH-Z19B NDIR infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO 2 in the air, with good selectivity, non-oxygen dependent and long life. Built-in temperature compensation; and it has UART output and PWM output.
Apr 23, 2020· Integrate a CO2 Sensor to Homeassistant using NodeMCU-32S (v ) + MH-Z19B and ESPHome This is a bit of a niche post, but it might help someone to accomplish this in less time than I did. The tutorial will be as easy as it gets.
May 26, 2020· I also got a MH-Z19B CO2 meter for testing to monitor the indoor CO2 levels. The initial feeling is that it does what it should. In general I have pretty good wifi coverage with a few Unifi access points. One of the sensors is in a building some 25 meters from the house where the wifi is not that strong, but the NodeMCU has no problem with this.

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.
Jan 08, 2020· But if I add mh-z19 config from the example (yaml number 2), wemos does not even connect to wifi. In this case If I use esphome-flasher tool in order to see logs via USB port, I'm getting logs as specified below. Problem-relevant YAML-configuration entries:
A description of what you want to happen. --> At the moment there is no ability to switch off daily auto calibration for the MH-Z19B sensor, while it is switched on by default. In case it works indoor the measurements it shows can be inadequate due to daily calibration without perfect ventilation. The shift of value can reach 300-400ppm!

Jun 27, 2019· MH-Z19. Description of problem: After esphome run, firmware is uploaded successfully and MH-Z19b seems to report values fine indefinitely. However, if I disconnect power and connect it again, sensor does not seem to report any values.
MagicHome with ESP8285. Yet another MagicHome RGB controller. I specifically had this one. Aside from it going 9-28V, there are no other external model numbers etc, however opening it up revealed a very different configuration inside, using an ESP8285 chip directly on the board.
