Projekt: Raum(-luft)sensor (Temp, Hum, Co2, VOC, LUX)

MH-Z19 liefert gute Ergebnisse. BME280 + Wemos Mini muss entsprechend wg. Gehäuse-Temperaturentwicklung angepasst werden. Dafür hat der BME280 aber noch Luftdruck. Interessant wären auch der Vergleich der Werte zwischen MH-Z19, iAQ Core ND und dem CCS811 hinsichtlich Kosteneffizienz / Langzeitstabilität und Kalibrierung, Rekalibrierung.

MH-Z19 CO_2 and Temperature Sensor — ESPHome

MH-Z19 CO_2 and Temperature Sensor¶. The mhz19 sensor platform allows you to use MH-Z19 CO_2 and temperature sensors () with ESPHome.. MH-Z19 CO_2 and Temperature Sensor. ¶ As the communication with the MH-Z19 is done using UART, you need to have an UART bus in your configuration with the rx_pin connected to the TX pin of the MH-Z19 and the tx_pin connected to the RX Pin of the MH-Z19 …

MH-Z14 and MH-Z19 CO2 Sensors • Wolles Elektronikkiste

· The MH-Z19 library by Jonathan Dempsey is, as the name suggests, written specifically for the MH-Z19 sensors. It works with both the B and C variants. My attempt to use it for the MH-Z14 failed. The MH-Z19 library is characterized by the fact that it uses many of the undocumented commands, such as the query of the range or the firmware version. Thanks to the many example sketches, it is easy ...

Unsinnsbasis

· Bei der Programmierung des CO2-Sensors MH-Z19B war aufgefallen, dass dessen Temperaturmessungen im Vergleich mehrere Grad über denen anderer Sensoren lagen. Auch die zum Vergleich genutzten Sensoren lieferten Werte, die tlw. um mehr als 1°C voneinander abwichen. Also schien ein Vergleich der Umweltsensoren mit Temperaturmessung sinnvoll. Neben sechs Exemplaren …

MH-Z19 CO2 sensor | MySensors Forum

· Loses callibration. It's mostly a chemical proces. The cool thing about the MH-Z14 and the even better MH-Z19 is that they use light spectrum analysis. They send infrared light, and measure how much of that light is absorbed in the spectrum that CO2 absorbs in. …

mh-z19 · PyPI

· The sudo might be necessary because mh_z19 module use Serial. The differences of the interface between each Raspberry Pi model are resolved inside this module. For example, serial device name is difference between Raspberry Pi 3 and older model, but mh-z19 module automatically detect the model and read from appropriate serial device.
