MHZ19C CO2 Sensor • ThingPulse

+

Description. The MHZ19C module is a nextgeneration CO2 sensor based on the nondispersive infrared (NDIR) principle. MHZ19C is the successor of the widely popular below for a comparison. The MHZ19C 400~2000ppm CO2 sensor has builtin temperature compensation and communicates over UART and PWM with the host controller.

CO2Sensor gegen Corona: Version mit ESP8266, MHZ19B und Tasmota. Wie das Umweltbundesamt in dieser Stellungnahme am 12. August 2020 schreibt, wird das CoronaInfektionsrisiko in Innenräumen durch Lüften stark verringert. Ein guter Indikator für ausreichenden Luftwechsel stellt die CO2Konzentration dar, die unter 1000 ppm bleiben sollte.
