In Arduino Uno / Nano / Pro Mini I2C bus is connected to A4 (SDA) and A5 (SCL), for Arduino Mega 2560 I2C bus is connected to D20 (SDA) and D21 (SCL) Here I am going to show you how to scan I2C address with a simple code. Code. I2C Scanner Arduino Code; I2C Scanner Arduino CodeC/C++. Write your code in Arduino IDE Software, save it. Select the port ( COM3) and choose your Arduino …
· Source Code/Program CCS811 Arduino Basic Interfacing. Though you can use any of the libraries for retrieving the value of CO2 & TVOC, I used the Adafruit library. The source code is given below. The default I2C Address of CCS811 is 0x5A while some of the CCS811 has an I2C Address of 0X5B. You can modify the I2C Address in the library file.

· Could you point me on some calibrated and easy to use CO2 sensor, preferably with some digital interface for long distance reading? What I'm trying to do is to make cheap device that measures temperature, humidity and CO2 (air quality) on 3 points in an apartment with just one Arduino. For temp/humidity I'm thinking to use DHT22, nice, cheap and 1-wire sensor (for up to 20m distance).
· 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 ...
· This is a NDIR, digital, auto-calibrating sensor, so it's pretty easy to use. I am now starting a new open source project, this time using Arduino. I uploaded a I2C library for this sensor on Github: K30_CO2_I2C_Arduino. This photo shows K30 connected to Arduino.
The CO2 concentration is calculated from the measured resistance and the temperature/relative humidity correction. It may be written as: CO2 = 410*ppm*(Rs/f_RH_T / Rs410/f_RH_T_410)^b. Where the exponent b is equal to - according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is ...
· After connecting the hardware according to the circuit diagram, the Arduino MQ135 sensor setup should look something like below: Calculating the R o Value of MQ135 Sensor. Now that we know the value of RL, let’s proceed on how to calculate the R o values in clean air. Here we are going to use to measure the CO2 concentration in the air.

· Mit anderen Worten: Man kann den SCD30 am Arduino-UNO wahrscheinlich problemlos auch am betreiben und braucht dann weder einen Pegelwandler noch eine Diode+Widerstand um den High-Pegel des I²C-Bus auf zu begrenzen. Wer sichergehen und die als Obergrenze für den High-Pegel einhalten möchte (immerhin kostet der Sensor ja fast 50,-€), …
· However, If your EZO-CO2 Sensor is blue (I2C mode) refer to the Datasheet on how to change modes. We are all finished with the wiring, now comes the fun part. Step 4: Flashing the code. If you do not already have the Arduino IDE software installed onto your computer, please do so now, as we’ll be using it for the last section of this tutorial.
· CO2 levels can have many negative effects on your body, here is a list of the values that one should be aware of and their effect: 250-400ppm -> Normal background concentration in outdoor ambient air. 400-1, 000ppm -> Concentrations typical of occupied indoor spaces with good air exchange. 1, 000-2, 000ppm -> Complaints of drowsiness and poor air.
· I2C Adressenkonflikt RTC und Co2. habe eine RTC DS1307 mit 0x68 Adresse und einen Co2Sensor K22 von Senseair auch mit 0x68 Adresse. Wie kann ich jetzt beide mit einem Uno zum Kommunizieren bringen?
