ArduinoSensor für CO² bzw. VOC KNXUserForum

· Habe den Thread gelesen und frage mich nun welcher VOCSensor am besten geeignet ist. So wie ich es verstanden habe, nutzen viele den IAQCORE CND Sensor. Der liegt preislich bei 3040 Euro, wohingegen bspw. der MP503 bei 12 Euro pro Stück liegt. Ich habe gesehen, dass beim zweiten eine Range von 101000ppm angegeben ist. Das ist sicher nicht optimal.

Beyond CO : Sensing VOCs in Indoor Air Protects Health ...

VOC sensors are produced by placing a semiconducting, nanocrystalline metal oxide on a substrate heated to between 300° to 400°C and measuring the conductivity. By adding dopants of noble metals, the sensitivity towards combustible gases (VOCs, carbon monoxide, natural gas) is influenced and allows a tuning of sensor performance for specific applications. The operating principle of a metal ...

SGP30 VOC sensor only shows low co2e values

· I''ve had the CCS811 VOC sensor for some time now but experienced it shooting up pretty high sometimes and not being very stable over time requiring a power cycle to get it back in line again. So I purchased the SGP30 VOC sensor after having really good luck with other temp / humidity sensors from the same company. I have noticed the same as you do that the sensitivity of the SGP30 sensor …

· All VOC/gas sensors use the same underlying technology: a tin oxide element that, when exposed to organic compounds, changes resistance. The ''problem'' with these sensors is that the baseline changes, often with humidity, temperature, and other nongasrelatedevents. To keep the values coming out reasonable, you''ll need to calibrate the sensor…

Flüchtige organische Verbindungen – Wikipedia

Flüchtige organische Verbindungen (englisch volatile organic compounds, kurz VOC) ist die Sammelbezeichnung für organische, also kohlenstoffhaltige Stoffe, die bei Raumtemperatur oder höheren Temperaturen durch Verdampfen (umgangssprachlich „Verdunsten“) in die Gasphase übergehen, also flüchtig sind. Das Gas Methan, CH 4, ist oft nicht eingeschlossen, manchmal explizit …
