MH-Z19 CO2 sensor | MySensors Forum

· Loses callibration. It's mostly a chemical proces. The cool thing about the MH-Z14 and the even better MH-Z19 is that they use light spectrum analysis. They send infrared light, and measure how much of that light is absorbed in the spectrum that CO2 absorbs in. …

Tornador-Gun Z10 vs Z20?! -

· Tornador-Gun Z10 vs Z20?! Hallo erstmal Ich überlege mir gerade mir eine Tornador-Gun für die Innenraumreinigung zuzulegen. Nun gibt es ja diese 2 Versionen, die weisse Z10 (anscheinend ein älteres Modell so wie ich das verstehe) und die schwarze Z20. Nun lese ich fast überall, das die Z10 für 6-8 bar Druck vom Kompressor ausgelegt ist, die Z20 allerdings nur für bar. Die einzige ...

arduino - MH-Z19 CO2 sensor giving diferent values using ...

· I have a MH-Z19 CO2 sensor, according the data-sheet I can obtain PPM values via UART and PWM. The difference between both method is the limit in the CO2 concentration, where UART I should have readings between 0-5000ppm, and via PWM I should have readings between 0-2000ppm. I just wanted to know if I can have the same readings using both methods, but after tried I'm realized …
