· Put the RZERO value in the library file you downloaded "": define RZERO Now we can begin the actual code for our Air quality monitoring project. In the code, first of all we have defined the libraries and the variables for the Gas sensor and the LCD. By using the Software Serial Library, we can make any digital pin as TX and RX pin. In this code, we have made Pin 9 as …

Krocker zur Anzeige der relevanten Werte des MQ135 und Verwendung der TemperaturKompensation. Der MQ135 Sensor wird verwendet um die Luftgüte, hier speziell das CO2 zu messen.
Material : MQ135 / Kabel / Arduino (Materialbeschaffung ) Der MQ135 Sensor ist ein Modul, welches die Konzentration verschiedener Schadstoffe in der Luft erfasst. Der Sensor gibt die erfassten Schadstoffwerte als analogen Wert aus. Diese können im Anschluss im seriellen Monitor ausgegeben oder
· ArduinoBibliothek für MQ135Gassensor: Hallo Leute, ich habe eine ArduinoBibliothek für den MQ135Gassensor erstellt und wollte sie mit Ihnen teilen. Der MQ135 ist ein relativ billiger Sensor, der auf verschiedene Arten von Gasen reagiert. Die Bibliothek ist für das häufigste Gas von ihnen gebaut Kohlendioxid, CO2. Ich s ...
· This is no good of course, so something must go wrong in the calculations in the MQ135 library. Or I am using a MQ135 sensor with a bad response curve. The next day I have tested the same with another MQ135, but the results were about the same. Wrong formula in the library. The formula to calculate the resistance of the sensor is wrong.

· MQ135 Module sensor has lower conductivity in clean air. When the target combustible gas exists, the sensor’s conductivity is higher along with the gas concentration rising. Convert change of conductivity to correspond output signal of gas concentration. MQ135 gas sensor has high sensitivity to Ammonia, Sulphide and Benzene steam, also sensitive to smoke and other harmful gases. It is with ...

· The datasheet claims that the MQ135 is sensitive for CO2, Alkohol, Benzene, NOx, NH3 and the Fig 3 shows the change in resistance depending on the concentration of these gases in the ambient air in ppm (of the total gas volume). It turns out the the general sensitivity is the roughly same for all the gases. This is where you think: Wait a minute!
· Download the MQ135 Library and include it in your Arduino IDE. Prepare the hardware setup with MQ135 gas sensor and 10KΩ Load Resistor (RL) After the 24 hours preheat process, perform the following procedures in the environment of 20 degree C/35% air temperature, and read the value of RZERO. include "".
· My correction value was around 22500. If you adjust the used library to the collected correction value you should end up with around ~400ppm outside. More detailed information about this MQ135 Sensor can be found here, unforcedly different documentations exits so make sure if you want to dig deeper that you are searching for the correct one.
Interfacing of MQ135 Gas Sensor with Arduino: In today’s world, we encounter different scenario where we see different gasses being emitted in atmosphere such as home appliances like air conditioner and industrial chimneys. Monitoring of these gasses is very important with safety point of view. Gas Sensors are very helpful in accomplishing this task.
· Guten Abend, ich bin gerade dabei meinen CO2Sensor MQ135 die auf dem Datenblatt vorgeschriebene Einlaufzeit laufen zu lassen. Dabei lese ich die Werte über den Seriellen Monitor aus. Nun zu meiner Frage: Ist es möglich ohne einen schon kalibrierten Sensor einen genauen Wert des CO2Gehalts in der Luft in ppm zu bestimmen? Aktuell liegt der angezeigte Wert bei ca. 140. Mir ist …
