Elecfreaks Octopus MG811 CO2 Gas Sensor



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 which is high allergic to CO2 and anti-interference to alcohol and CO. It is of high performance and quick response with loaded signal amplification circuit even in different temperature and humidity environment. Besides, the heating circuit on-board helps to convert to stable 6V voltage from 5V directly that improves the adaptability of the module.
