MG-811 Carbon Dioxide Sensor Module (Carbon dioxide sensor) is a carbon dioxide sensor (CO2) sensor is a Metal Oxide Sensor sensor, which must heat the tank to the specified level. (With the method of supplying power) will cause heat vapour and separate CO2 from the air.  This sensor module has an MG-811 onboard as the sensor component. A signal output circuit for heating the sensor The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO. The output voltage of the CO2 increases.

Useful for greenhouses and medical projects.  Sends an analog signal that decreases as the concentration of CO2 increases. This module also includes a digital output pin with TTL output. The Potentiometer on board is used to set the Digital Output Setpoint.  After setting the potentiometer threshold, once that threshold is reached, an LED on the sensor will illuminate and the digital pin will give a HIGH voltage signal.

Pinout:

  1. VCC: 6V ( You can use a 4 AA battery holder for this )
  2. AOUT: Analog Output (voltage decreases as CO2 Levels increase)
  3. DOUT: Digital Output that goes HIGH when the threshold is reached (set the threshold by turning the onboard potentiometer)
  4. GND: 0V
