Description

There 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 (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

For all Grove users (especially beginners), we provide you guidance PDF documents. Please download and read through Preface - Getting StartedandIntroduction to Grove before your using of the product.


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.

Hard to fix
This O2 sensor is not easy at all to fix on a support due to the electronic compounds at the back of the card.

    What's the output voltage at 25%, 20% and 15%?<br/><br/>

    According to the code, the concentration = Vout*100*0.21/2.So do a simple math, 25%--2.38V &nbsp; &nbsp;20%---1.90V &nbsp; &nbsp;15%---1.42VBut this is just a&nbsp;theoretical value,cause the relation between concentration and voltage is not&nbsp;&nbsp;strictly&nbsp;linear.So the real value should be a little bit different
