Grove - Gas Sensor (O2) [Discontinued] Brand_Extech You’ll need a microcontroller withThere are sevral kind of Gas Sensor we are providing in Bazzar, if you don't know which one is the right sensor your want, please refer to the tutorial How to choose a gas sensor? Grove Gas Sensor (O?) 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
