Octopus CO2 Gas Sensor (MG811)

Description

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 as theirs.

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 an industrial grade that is highly allergic to CO2 and anti-interference to 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 stable 6V voltage from 5V directly 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 seal preservation while the sensor is not in use in case the probe gets “poisoned” due to the long time exposure in the air or you have to heat it continuously for 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 it to get an accurate value.

Characteristic

Working voltage of the probes: 6v
With the booster circuit inbuilt, it supports input DC 3.7~5V and the current over 500mA.
OCTOPUS electronic bricks.
Easy connection.
