CO2 = 410*ppm*(Rs/f_RH_T / Rs410/f_RH_T_410)^b. Where the exponent b is equal to - according to Mad Frog. And where Rs410 is the sensor resistance measured in clean air (410 ppm of CO2) and f_RH_T_410 is the correction factor at the moment that the clean air sensor resistance is measured. Here we assume that the correction factor as a ...
The CO2 Sensor Arduino Compatible is the first CO2 sensor in OSHW 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 has MG-811 sensor …

2019-01-10· Arduino Library for Sandbox Electronics NDIR CO2 Sensor with UART/I2C Interface - GitHub - SandboxElectronics/NDIR: Arduino Library for Sandbox Electronics NDIR CO2 Sensor with UART/I2C Interface
But here's the problem: Arduino can't provide enough power to run this sensor from its pins - sensor's heater requires 150 mA, while Arduino pin can provide no more than 40 mA, so if attached directly, Arduino pin will burn and sensor still won't work. So we must use some kind of current amplifier that takes small input current to control large output current.
2016-05-05· The MQ-2 sensor has 4 pins. Example: Gas Sensor with Arduino In this example, you will read the sensor analog output voltage and when the smoke reaches a certain level, it will make sound a buzzer and a red LED will turn on. When the output voltage is below that level, a green LED will be on.
