The MG-811 Carbon Dioxide Sensor Module is a Metal Oxide Sensor that requires heating to a specified level to separate CO2 from the air. It is highly sensitive to CO2 and less sensitive to alcohol and CO. The module sends an analog signal that decreases as CO2 concentration increases. It also includes a digital output pin with TTL output. The onboard potentiometer is used to set the Digital Output Setpoint. Once the threshold is reached, an LED on the sensor will illuminate, and the digital pin will give a HIGH voltage signal.
Pinout:
- VCC: 6V (You can use a 4 AA battery holder for this)
- AOUT: Analog Output (voltage decreases as CO2 Levels increase)
- DOUT: Digital Output that goes HIGH when the threshold is reached (set the threshold by turning the onboard potentiometer)
- GND: 0V
Package Includes: 1 x MG811 Air Carbon Dioxide (CO2) Sensor Module
