Grove - Oxygen Sensor (MIX8410)

Grove - Oxygen Sensor(MIX8410) 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 environmental protection. Grove - Oxygen Sensor(MIX8410) is an organic reaction module, it can provide a little current while putting it in the air, we don't need to provide external power to it, and the output voltage will change as time current changes.

Note: The sensor value only reflects the approximated trend of gas concentration in a permissible error range, it DOES NOT represent the exact gas concentration. The detection of certain components in the air usually requires a more precise and costly instrument, which can not be done with a single gas sensor. If your projects aim to obtain the gas concentration at a very precise level, then we do not recommend this gas sensor.

Note:

• When in use, the maximum input voltage cannot exceed 5.5V
• This sensor needs to be preheated for 5-10 minutes before use
• Keep the sensor out of volatile solvents 
• Prohibit storing and operating the sensor in an acidic or alkaline environment

• High sensitivity (0.1±0.03 mA) with linear output
• High stability with <10s response time
• Environmental protection design
• Advanced anti-leakage technology which greatly reduces the probability of leakage
• Low output current for longer sensor life
