Seeed Studio 101020002, Grove-Oxygen Sensor O2 (ME2-O2-Ф20) for ME2-O2-20 for Grove System

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 detectors and analyzers. 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.
