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

09/10/2016· 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 …

22/01/2016· - MH-Z19 (old version) - MH-Z19B - Senseair S8 - Netatmo Results: From the observation of the CO2"-curves over time, i come to the following conclusion: a) The Netatmo and the Senseair S8 Sensor correlated very well over time. Curves were quite smooth without significant correction-jumps. Measurements seem to be the most trustworth and comprehensible. b) Compared to the Natatmo and …

CO2-Sensor MH-Z19B - Unsinnsbasis

10/11/2020· Der MH-Z19B ist ein CO2-Sensor, mit dem man eine CO2-Ampel selbst realisieren kann. Durch die Corona-Pandemie (COVID-19) sind zur Messung der Luftqualität in Räumen, die von mehreren Personen gleichzeitig benutzt werden, vermehrt CO2-Sensoren im Einsatz ( in Klassenräumen in Schulen). Der CO2-Wert gibt einen Hinweis darauf, wie „verbraucht” die Luft ist - indirekt wird daraus …

The MH-Z19B CO2 sensor bible - eMariete

27/12/2020· The MH-Z19B CO2 sensor is fantastic. A cheap, accurate CO2 sensor (for the price it has) and very easy to a doubt, one of the most used sensors with Arduino, ESP8266, EPS32 and the like. Also the CO2 sensor MH-Z19C (although a bit special) is a good sensor, as long as you know what there is to know about it and what makes it special.
