SeeedStudio - Grove - Gas Sensor(O2) - DIY Maker Open Source BOOOLE

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 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
