MHZ19B (1-1/1) -

MHZ19B-Pinout. Im Datenblatt konnte kein Hinweis auf die Defaulteinstellung des Messbereichs gefunden werden, es scheint so, als ob verschiedene Typen des Sensors verkauft würden. Der eingestellte Messbereich kann über die UART abgefragt werden: mhtz19b_uart_get_ Die Hardware . Die Verdrahtung mit dem Arduino wird etwas erschwert, da die Anschlüsse des MHZ19B …

MH-Z19 CO2 Sensor - Home Assistant

MH-Z19 CO2 Sensor. The MH-Z19 is a small non-dispersive 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 ...
