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 …

Review and Test of the MH-Z14A NDIR CO2 Sensor

09/03/2018· The MH-Z14A measures CO2 concentrations using absorption of infra-red light. These devices are available on eBay, Amazon and other places from about $20. Ignore the capacitor across the power pins - this was a failed attempt by me to improve the reliability of the analog outputs. My initial impressions of the module were pretty favourable.

Air Quality: CO2 Sensor MH-Z14 | MySensors Forum

16/11/2014· MH-Z14A vs MH-Z19 ? Their price is very similar and kinda meh in comparison but which should one prefer and when? I can see Z19 having some response time lower but power consumption higher... Maybe someone here already made the comparisons and can share that useful information into this thread, so that others would also know what to pick and why? Thanks . Reply Quote 0. 1 Reply …
