Capteur CO2 MH Z19B

MH-Z19C CO2 Sensor • ThingPulse

Description. The MH-Z19C module is a next-generation CO2 sensor based on the non-dispersive infrared (NDIR) principle. MH-Z19C is the successor of the widely popular MH-Z19B.See below for a comparison. The MH-Z19C 400~2000ppm CO2 sensor has built-in temperature compensation and communicates over UART and PWM with the host controller.

MH-Z19, mesurer la concentration en CO2. Test avec ...

Feb 12, 2021 · Si vous n’avez lu l’article précédent, le capteur MH-Z19 de la société Winsen est plus précis que le capteur environnemental MQ135.Il est beaucoup plus cher (environ 20€) mais la mesure du taux de CO2 ne nécessite pas de “bidouille” mathématique.On récupère directement la valeur exprimée en ppm sur la broche PWM ou sur la sortie URT (port série).

Jun 20, 2021 · Sensor MH-Z19B. Carbon Dioxide, more know for its global warming effect, is more relevant for indoor sensing. When used outdoor, concentration levels are low with small variation, and without direct health impact (but strong indirect humanity impact). We recommend this sensor only for academics working on CO2.
