CO2_Sensor_SKU_SEN0159-DFRobot

This is the first CO2 sensor on the opensource hardware 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. Once the CO2 concentration is high enough (voltage is lower than threshold), a digital signal (ON/OFF) will be released.

ESP32 Arduino: Temperature, humidity and CO2 concentration ...

Jun 11, 2018· Nonetheless, for the sake of simplicity, we will assume a linear behavior of the ADC in the 0 V to V range, like we did in the previous tutorial about interacting with the CO2 sensor. Naturally, this will introduce some imprecision in the CO2 measurements, which means that this code should not be used if you need very accurate measurements.
