CO2-Sensor an ESP32 - Spannungsversorgung - Deutsch ...

· Ich möchte einen NDIR-CO2-Sensor (MH-Z14A) an einem ESP32 (Heltec WifiKit32) zumindest kurzzeitig auch im Batterie-Modus betreiben. Der Sensor benötigt eine Betriebsspannung von 5V, die der ESP32 im Batterie-Modus nicht liefert. Deshalb habe ich ein Step-up-Modul (MT3608) zwischen den 3,3V Ausgang des ESP32 und den Sensor geschaltet.

MH-Z14A CO2 Meter Tutorial with Arduino, ESP8266 or ESP32

· MH-Z14A CO2 Sensor. For our Corona CO2 sensor, we use the MH-Z14A that has an operation voltage between and Therefore, the CO2 sensor can run on all Arduino microcontroller with an operation voltage of 5V. For ESP8266 and ESP32 microcontroller with an operation voltage of , we have to use the 5V output from the USB connection.

Measuring CO2 with MH-Z19B on ESP32 with MicroPython | The ...

The ESP32 board talks to the MH-Z19B sensor via UART (another option is PWN). According to the datasheet, the sensor needs 5V voltage, ... Then, the method waits for a while to let the sensor measure CO2 and send the measurement back. After reading the data, the method calls the is_valid() routine that makes sure that the returned data is correct by validating its checksum and a few other ...

Build your own CO2 measuring device easily and ...

The CO2 sensor also has an analogue output, but we don’t use it because the measuring accuracy is lower here. We now connect the pins of the sensors to the pins on the ESP32 with circuit wire according to the wiring diagram and then check again that the wiring is in accordance with the wiring diagram to avoid any trouble later. Now we put our assembled circuit board into the housing and fix ...
