Grove - Gas Sensor(O2) copy

![enter image description here][1] **DESCRIPTION** How to choose a gas sensor ? Grove-Gas Sensor (O₂) is a kind of 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. It’s very suitable for detecting oxygen concentration in the environment protection. **Features** High-precision High sensitivity Wide linearity range Strong anti-interference ability Extraordinary reliability **Documents** Please visit our [wiki][2] page for more info about this product. It will be appreciated if you can help us improve the documents, add more demo code or tutorials. For technical support, please post your questions to ourforum.
