The Arduino keeps reading the CO2 level from the gas sensor and if the current CO2 level increases beyond the threshold level, it activates the buzzer and sends a HIGH logic to relay connecting pin switching the air purifier ON. When the CO2 level is again reduced to a permissible level, the Arduino switches OFF the air purifier by sending a LOW logic at the relay connecting pin.

Here we are explaining some important parts of the MQ135 Arduino code. The code uses the Adafruit_GFX, and Adafruit_SSD1306, and libraries. These libraries can be downloaded from the Library Manager in the Arduino …
These two jumper cables are important as they will allow both the EZOCO2 sensor and the Arduino Uno board to communicate with each other. (image number 2 above) Next, place the red jumper cable into the 5V pin. And finally, place the black jumper cable into any of the 2 GND or ground pins near the 5V pin. These two jumper cables will now supply power and a ground line from the Arduino Uno to ...
20210725· The SCD30 is an NDIR sensor, which is a ''true'' CO2 sensor, that will tell you the CO2 PPM (partspermillion) 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 ...
