Gravity: I2C Oxygen Sensor

The Gravity I2C Oxygen Sensor operates on electrochemical principles, enabling accurate and convenient measurement of ambient O2 concentration. It offers high anti - interference, stability, and sensitivity. This Arduino - compatible sensor is ideal for portable devices, air quality monitors, and areas with poor air circulation like industries, mines, and warehouses. This compact DFRobot sensor supports I2C output. It can be calibrated in the air to precisely measure environmental oxygen concentration. Compatible with many mainboards such as Arduino Uno, ESP32, and Raspberry Pi, it has an effective range of 0 - 25%Vol and a resolution of 0.15%Vol. It accepts a wide input voltage from 3.3V to 5.5V and has a long lifespan of over 2 years. With a simple Gravity interface and useful sample code, you can easily build your own oxygen concentration monitor. Key features include high sensitivity, an I2C interface, compatibility with 3.3V and 5V micro - controllers, and polarity protection. Its specifications cover gas detection (oxygen), operating voltage, output signal, measurement range, and more.

Using the Gravity I2C Oxygen Sensor is easy. First, connect it to a compatible mainboard like Arduino Uno, ESP32, or Raspberry Pi. Make sure the input voltage is within the 3.3V to 5.5V range. You can calibrate the sensor in the air for accurate readings. When measuring, place it in the area where you want to check the oxygen concentration. Note that the sensor's measurement range is 0 - 25%Vol, with a maximum limit of 30%Vol. The response time is within 15 seconds. Keep the operating temperature between - 20℃ and 50℃, and the humidity between 0 - 99%RH without condensation. The pressure should be within standard atmospheric pressure ±10%. For maintenance, keep the sensor clean and dry. If there are any issues, refer to the product wiki or other available documents. The sensor has a lifespan of over 2 years in the air, but proper use and storage can help it last longer.
