1. What are gas sensors? How do they work?

• Gas sensors (also known as gas detectors) are electronic devices that detect and identify different types of gasses. They are commonly used to detect toxic or explosive gasses and measure gas concentration. 
  Gas sensor detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and concentration of the gas can be estimated.

2. How to use MG-811 Gas Sensor?

• Power the module with 5V and you should notice the power LED on the module to glow and when no gas it detected the output LED will remain turned off meaning the digital output pin will be 0V. Remember that these sensors have to be kept on for pre-heating time before you can actually work with it. Now, introduce the sensor to the gas you want to detect and you should see the output LED to go high along with the digital pin, if not use the potentiometer until the output gets high. Now every time your sensor gets introduced to this gas at this particular concentration the digital pin will go high (5V) else will remain low (0V).

3. What are the typical applications of the MG811 sensor?

• Typical applications include:

  Air Quality Control: Monitoring and controlling indoor air quality.
  Fermentation Process: Monitoring CO2 levels during fermentation in brewing and other processes.
  Indoor Air Monitoring: Ensuring safe CO2 levels in indoor environments

4. What is the operating voltage for the MG811 sensor?

• The MG811 sensor typically operates on a DC voltage of around 6V. It includes an on-board heating circuit to maintain the optimal temperature for accurate readings

5. How is the output of the MG811 sensor interpreted?

• The output of the MG811 sensor is an analog voltage that decreases as the CO2 concentration increases. This voltage can be read by a microcontroller or other data acquisition systems to determine the CO2 concentration in the air
