Gravity: Analog CO2 Gas Sensor For Arduino (MG-811 Sensor ...

Here is the Arduino-based CO2 sensor designed by DFRobot lovely engineer. This is the first CO2 sensor in the 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 (the voltage is lower than the threshold), a digital signal (ON/OFF ...

Measuring CO2 Concentration using Arduino and MQ-135 Sensor

This project looks into designing and testing a CO2 sensor using an Arduino UNO. An MQ-135 sensor is tested under different conditions in order to obtain detection limits and measure trends. The literature shows that there is around 400 PPM of carbon dioxide in the atmosphere, the average indoor values range from 35-450 PPM and the maximum acceptable level is around 1000 PPM. The MQ-135 ...

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

2021-07-25· 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 ...
