MH-Z19 CO2 Sensor - Home Assistant

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 increase ventilation.

2021-03-24· The sudo might be necessary because mh_z19 module use Serial. The differences of the interface between each Raspberry Pi model are resolved inside this module. For example, serial device name is difference between Raspberry Pi 3 and older model, but mh-z19 module automatically detect the model and read from appropriate serial device.

2018-11-05· 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.

RPI Node-Red: MH-Z19 CO2 Sensor • T³ Alliance

2019-12-23· The MH-Z19 is an Infrared CO2 sensor that talks to the raspberry pi over a serial port. It works by shooting an infrared beam through a sample of some air and measuring the specific frequency of light that CO2 absorbs, then it can calculate the Parts per million CO2 content. Getting Started: Wiring: Power (Red Wire) –> 2 (5v) Ground (Black Wire) –> 6 (GND) Tx (Blue Wire) –> 8 (#14 TXD ...
