CO2 meter using NDIR infrared MH-Z14 sensor library for ...

MH-Z14 NDIR Infrared gas module is a common type, small size sensor, using non-dispersive infrared (NDIR) principle to detect the existence of CO2 in the air, with good selectivity, non-oxygen dependant and long life. MH-Z14 has a PWM output, with a sensitivity range of 0ppm to 2000ppm CO2, an accurancy of ±200ppm. The cycle is 1004ms±5%, given the duty cicle Th (pulse high), Tl is 1004-Th ...

MH-Z14A CO2 sensor | MySensors Forum

· Seems like my MH-Z14 sensor is faulty after all. My problem was that the sensor reported the value 562 like 80% of the time. I was hoping I could solve this by using the serial method to read the value from the sensor but I stil had the same problem. Luckily I just received another MH-Z14 so I could replace it. Now it seems to work better.

CO2-Sensor MH-Z19B - Unsinnsbasis

· 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 …
