Product Description

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.

Caution

The module belongs to electrochemistry CO2 and the probe heats itself when working, please do not touch in case getting hurt.

Please make a seal preservation while the sensor is not in use in case the probe getting “poisoned” due to the long time exposure in the air or you have to heating continuously another 48 hours to activate it! The MG-811 probe belongs to the category of electrochemistry sensor, please make a proving operation for it before using to get an accurate value.

Awesome service with super fast delivery. The chat option really helped me choose the products, know they were in stock and would be delivered in time. The items were posted the same day and I couldn't believe it when they arrived from Perth to Melbourne in 3 days! Thanks for your wonderful support - our students were able to complete their robotic projects in time.
