MHZ19 CO2 sensor

+

The MHZ19 is a CO2 sensor. Measurements are provided in parts per million (ppm) over UART and PWM. The ppm value ranges from 0 (theoretically) to 2000 or 5000, depending on the sensor settings. In UART mode, additional commands are available to configure the sensor. Note that the sensor requires considerable time before accurate measurements are provided. Files: file Interface ...

20191222· Ik heb een aantal van die BME 280 sensoren naast elkaar aan 1 ESP32 Gehad om hun gedrag te bekijken. Ik kwam er achter dat ze temperatuur veranderingen goed aangeven, maar bij elke keer opnieuw opstarten hadden ze een nieuwe offset. Die offset kreeg ik niet weggewerkt. Voor CO2 was ik nog aan het rondkijken. De MHZ19B ziet er interessant uit.
