DFRobot Gravity: i2C O2 Sensor


This is an Arduino 02 gas sensor. 

This Oxygen Sensor is based on electrochemical principles and it can measure the ambient O2 concentration accurately and conveniently. With high anti-interference ability, high stability and high sensitivity, this Arduino-compatible oxygen sensor can be widely applied. It can be made portable device and used as a air quality monitoring device for industries, mines, warehouses and other spaces where air does not circulate well.

This compact dfrobot oxygen sensor supports I2C output, it can be calibrated in the air, can accurately measure the oxygen concentration in the environment. It is compatible with many mainboards like Arduino Unoesp32Raspberry Pi and so on. Its effective range is 0~25%Vol, and resolution can reach to 0.15%Vol. It supports wide range input voltage: 3.3V to 5.5V. Moreover, the lifetime is as long as 2 years. With simple Gravity interface and practical sample code, you can build your own oxygen concentration monitor easily and conveniently.
