mq135 co2 sensor arduino code

Luftqualitätssensor MQ135 Kallibrieren

· Nun kommt der Sensor nach 24 Stunden auf 500ppm CO2Anteil. Diese "500" sind Deine Referenz. Weicht der Wert ab (473/523) dann sagst Du dem Arduino "mach was". Es wird also nur verglichen. Willst Du richtig messen, dann brauchst Du eine richtige Referenz. Du brauchst also einen Raum, in dem Du verschiedene Werte simulieren kannst.

Measuring CO2 with MQ135 – Pocket Science Lab

· A MQ135 sensor on a small PCB. The MQ135 is a cheap gas sensor that is primarily intended for detecting the presence of flammable gases. It is marketed as a generalized “air quality” sensor, rather than precision device for measuring the concentration of any specific gas. Nevertheless, according to the data sheet the MQ135 is capable of ...

IoT Based Air Quality Index Monitoring with ESP8266 MQ135

· MQ135 Air Quality Sensor. The MQ135 gas sensor senses the gases like ammonia nitrogen, oxygen, alcohols, aromatic compounds, sulfide and MQ3 gas sensor has a lower conductivity to clean the air as a gas sensing material. In the atmosphere, we can find polluting gases, but the conductivity of the gas sensor increases as the concentration of polluting gas increases.
