- MG-811 Carbon Dioxide Sensor Module is a carbon dioxide sensor (CO2) sensor that is a Metal Oxide Sensor.
- Useful for greenhouses and medical projects.
- This module also includes a digital output pin with TTL output.
- The Potentiometer on board is used to set the Digital Output Setpoint.
MG811 Carbon Dioxide Sensor
The carbon dioxide sensorĀ has an MG-811 onboard as the sensor component. The MG-811 is highly sensitive to CO2 and less sensitive to alcohol and CO.Ā The output voltage of the CO2 increases.Ā
Pinout:
- VCC: 6V ( You can use aĀ 4 AA battery holderĀ 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 xĀ MG811 Carbon Dioxide Sensor
