      Description

      There are sevral kinds 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.

      What's the output voltage at 25%, 20% and 15%?
      on Jul 11,2017
      Replyupvote ()
      According to the code, the concentration = Vout*100*0.21/2.So do a simple math, 25%--2.38V 20%---1.90V 15%---1.42VBut this is just a theoretical value,cause the relation between concentration and voltage is not strictly linear.So the real value should be a little bit different

      I bought this module at February this year, but seldom use it until my other component finished.I supply DC5V to this module, but it always output at DC3.22V after 10-15 mins.And the output won't change with the different oxygen content.1. How can I make sure the sensor is available?2. The product life-time of sensor is 2-year, right? I always kept the sensor in the orginal container.Above all, tks.

      Hi there~ The O2 sensor needs about 20-30 minutes to preheat, and right now it is noly compatible with Arduino. Please tell us more detail, so that we can help you.If you can take a picture or a screenshot of the data will be better. You can email us via # techsupport@seeed.cc # Regards.
