MH Z19C ESP32

GPIO Pin # for RX2 and TX2 ? (Solved) - ESP32 Forum

Jul 31, 2019· Each dev board is different. I suggest you look for an eschematic for that particular one, or use a multimeter to check where those pins are connected. Later you can use the ESP32 module datasheet to check what pin number it is. BTW, if I am not mistaken, you can route UART2 pins (TX2-RX2) to any gpio pin of the ESP32 you want, in code. Top.

Testing the MH-Z19 Infrared CO2 Sensor Module • Circuits

Jul 11, 2017· Introduction: In this article we will do a simple functional test of the MH-Z19 CO 2 sensor by connecting it to a raspberry pi 3 UART and run a simple datalogger python program which prints results to the screen and stores results in a csv formatted file. The file can later be imported to matlab or excel for further analysis or just plot a graph of the collected data.

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

Jun 12, 2021· After the addition phase, the CO2 concentration slowly decreased due to the leakage of the measuring chamber. Here, too, the MH-Zxx sensors reacted more slowly and delivered correspondingly higher values. Here is an example of a result for the MH-Z14 sensor: MH-Z14 vs. Technoline WL 1030. The results for the MH-Z19C looked very similar.
