Publish the CO2 concentration of an MH-Z19 ... - DIY Projects

2021-02-12· The MH-Z19 is a self-calibrated sensor, ie the measurement sent by the sensor does not require any mathematical treatment. In other words, the CO2 content expressed in ppm (parts per million) is recovered. The MH-Z19 has a PWM output and a UART digital interface (serial port). For this tutorial, we will already start by exploiting the PWM output. Measuring range: 0 – 5000ppm: Precision: ± ...

Arduino for Greenhouse, Garden or Growbox / Updated April ...

The MH-Z19 has 3 ways of reading the CO2 concentration. It has a Tx/Rx UART, It has an analog output and it has a PWM input. The latter is for my purposes the easiest to use. The CO2 concentration = 2000 x (TH-2ms)/(TH+TL-4ms) As the total cycle is always 1004 ms we only need to read TH and can simplify the formula to Cppm=2x(TH-2ms). I am measuring CO2 once every hour. With regard to the ...

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. Note: the new version MH-Z19B requires the VIN to be ...
