In Schulen wurde in Zusammenhang mit der Covid19 Pandemie der Ruf nach sogenannten CO2Ampeln laut. Diese Geräte messen den Co2 Anteil in der Umgebungsluft und visualisieren die Messwerte mit Hilfe einer Ampel. Sobald bedenkliche Mengen CO2 in der Raumluft vorhanden sind, wechselt die Ampel von einem grünen Licht schrittweise über ein gelbes Licht zu einem roten Licht. Dadurch wird ...

· MHZ19C. Using Arduino Sensors. elmonoloco January 29, 2021, 11:32am 1. Hi, Currently I’m trying to print some readings with ESP32 from the MHZ19C (Co2 and temperature sensor), with a pretty simple program that I feel like should work. But after opening the serial monitor and pressing the reset button, i get something really weird:

Testing the MHZ19 Infrared CO2 Sensor Module • Circuits

· Instead of calibrating at 0ppm CO2 (nitrogen), the sensor is calibrated at 400ppm CO 2 (outdoor air is actually very close to 400ppm), then 400 ppm is subtracted from the newly calculated offset value. Fresh air calibration is best for sensors in manufacturing settings or greenhouses where the sensor is constantly exposed to different CO 2 levels.

MHZ19 CO2 sensor

MHZ19 CO2 sensor driver. Description. 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 …
