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

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) will be released. It has MG-811 sensor module which is highly sensitive to ...

LM35 Temperature Sensor Arduino Tutorial (3 Examples)

However, this function will not actually return the output voltage of the sensor. Arduino boards contain a multichannel, 10-bit analog to digital converter (ADC), which will map input voltages between 0 and the operating voltage (5 V or V) into integer values between 0 and 1023. On an Arduino Uno, for example, this yields a resolution ...
