Hello has anyone worked with this sensor before? A friend of mine gave me this sensor but I couldn’t find anyone working with this sensor online. [Here](US $18.50 | New Original SenseAir S8-0024 S8-4B 004-0-0024 Infrared CO2 Carbon Dioxide Sensor S8 0024 https://a.aliexpress.com/_m0rAYII ) is a link. …

Hello, Thank you. It looks like G+ is positive G0 is negative that is the power pins.There is Out1, Out3, Out4, S1 and S2. S1 is Calibration. S2 is Somekind of testing Out1 is Output Alarm. Not sure what this all is. I did mange to see some people with this sensor But not this type of pinout …

Sadly, this part is a threshold device. It is not suitable for anything but a very high CO2 level alarm. The datasheet describes the operation. S1 is for calibrating with fresh air. Out1 is pulled to ground if the CO2 exceeds 8000 ± 1000 ppm. The accuracy in general is no better than ±400 ppm which…
