Octopus MG811 CO2 Gas Sensor is a CO2 electronic brick in our OCTOPUS series, the basic design for the outlook, PCB fixing holes and connections are the same with them. The higher the CO2 concentration is, the lower the output voltage would be. The users can read the CO2 value easily after checking our brochures and coding samples.
The CO2 probe is made with industrial grade materials which are highly allergic to CO2 and are not affected by alcohol and CO. It is of high performance and quick response with a loaded signal amplification circuit even in different temperature and humidity environments. Besides, the heating circuit on-board helps to convert to a stable 6V voltage from 5V which improves the adaptability of the module.
Caution
The module belongs to electrochemistry CO2 and the probe heats itself when working, please do not touch when in use.
Please make sure you seal the sensorwhen it is not in use to avoid damage to the probe due to long exposure in the air or you will have to heat it continuously for 48 hours to reactivate it!
Hardware Connection
The module connects to the A0 of the Arduino UNO through a Dupont wire. The Arduino main board much be powered with extra connection(7.5V-9V).
- Working Voltage: DC 3.7~5v
- Working Voltage of the probes: DC 6v
- Working Amperage: 500mA
- Connection Mode: G-GND?V-VCC?S-pin signals
- Size: 31 x 48mm
- Net Weight: 9.6g
