Measuring CO2 with MQ135 – Pocket Science Lab

04/03/2021· 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 measuring the concentrations of several gases, one of which is CO 2. This makes it ...

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 ...

DFRobot CO2 Sensor (Arduino compatible): ...

For that reason, this CO2 sensor is designed by DFRobot engineer. This is the first CO2 sensor in Arduino market. The output voltage of the module falls as the concentration of the CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released. It ...
