Grove - Oxygen Sensor(ME2-O2-Ф20)

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 analog 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.

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.
