Tip

We’ve released the Seeed Gas Sensor Selection Guide, it will help you choose the gas sensor that best suits your needs.

Grove – Oxygen Sensor(ME2-O2-Ф20) is a kind of analogue gas sensor to test the oxygen concentration in air, which is based on the principle of the electrochemical cell to the original work. You can know clearly the current oxygen concentration when you output voltage values proportional to the concentration of oxygen and refer to the oxygen concentration linear characteristic graph.

This Grove O2 sensor can be used to make simple oxygen level detector and analyzer. It can measure O2 concentration within a range of 0 to 25% Vol and the max detecting concentration is 30% Vol. It’s very suitable for detecting oxygen concentrations in the Arduino environment project.

This sensor needs to be connected with the grove Pi+ which supports raspberry pi or base shield which supports Arduino Uno. You may also need Grove cable as a connector. Besides, there is a related product- Grove gas sensor(MQ2) who has a wiki about how to set up a gas sensor with Seeeduino. Similarly, you can begin your own project with this sensitive gas sensor and have fun!

Note

The sensor value only reflects the approximated trend of gas concentration in a permissible error range, it DOES NOT represent the exact gas concentration. The detection of certain components in the air usually requires a more precise and costly instrument, which can not be done with a single gas sensor. If your projects aim to obtain the gas concentration at a very precise level, then we do not recommend this gas sensor.
