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

· 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. During the operation of the MH-Z14A the current consumption is around 100mA and therefore not suitable for a battery powered project. At the initial start of the CO2 ...

CO2-sensor with mega2560 - Project Guidance - Arduino Forum

· Thank you very much for your help. I swapped the TX and RX wiring on the arduino, now it is contrary to what the instructions said. That brought a small improvement. I still get no automatic measurement reply about the CO2, but when ask about the preinstalled altitude properties of the sensor I get some kind of reaction from the sensor. I used ...

CO2-Sensor gegen Corona: Version mit Arduino UNO und ...

· Wenn man den CO2-Sensor SCD30 an einem Arduino UNO betreibt, dessen IO-Pins 5V ausgeben können, dann würde ich immer einen Level-Shifter verwenden, um den SCD30 vor zu hohen Eingangsspannungen zu schützen. Im Prinzip wäre das zwar unnötig, solange die SCL- und SDA-Pins des UNO im Open-Drain-Modus arbeiten, aber wenn durch einen SW-Fehler die SCL- und SDA-Pins …

Arduino | Adafruit SCD-30 - NDIR CO2 Temperature and ...

· The SCD-30 is an NDIR sensor, which is a 'true' CO2 sensor, that will tell you the CO2 PPM (parts-per-million) composition of ambient air. Unlike the SGP30, this sensor isn't approximating it from VOC gas concentration - it really is measuring the CO2 concentration! That means its a lot bigger and more expensive, but it is the real thing. Perfect for environmental sensing, scientific ...

Measure CO2 & TVOC using CCS811 Gas Sensor & Arduino

· Overview. In this tutorial, we will interface CO2 & TVOC Gas Sensor CCS811 with Arduino & measure CO2 & TVOC in the air. The CCS811 Air Quality Breakout Board is a digital gas sensor capable of sensing a wide range of Total Volatile Organic Compounds (TVOC) & equivalent carbon dioxide (eCO2) with metal oxide (MOX) levels. We can thus use this sensor to identify the air …
