Capteur de CO2 MHz14 MHz19 MHz19 Unterschié

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 ...

MHZ14 und MHZ19 CO2 Sensoren • Wolles Elektronikkiste

MHZ19 CO2 Sensor. The MHZ19 is a small nondispersive infrared sensor that can measure CO2 level. High CO2 levels can lead to drowsiness, poor concentration, loss of attention or increased heart rate. The CO2 level outside is around 400ppm, but inside levels can reach between 1000 and 5000 ppm. High CO2 levels indicate that you should ...

ESP32 Co2 MHZ19 – MyRFX Domotique

Je vous propose de mesurer le Co2, de l’afficher sur un écran OLED et de transmettre cette valeur à DOMOTICZ. En combinant le MHZ19 et un ESP32 LOLIN vous obtiendrez un capteur performant. Le MHZ19 est communiquant de deux façons , soit par une liaison série, soit par une sortie PWM. Dans ce montage c’est la sortie PWM qui est retenue.
