Seeed Studio Grove – Oxygen Sensor(ME2-O2-Ф20)


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.
