DFRobot Gravity I2C Oxygen Sensor

The DFRobot Gravity I2C Oxygen Sensor operates based on electrochemical principles, measuring ambient O2 concentration accurately and conveniently.

Electrochemical

• Expose To Extreme Conditions: Avoid exposing the sensor to environments where it might be damaged by extreme conditions.,
• Reverse Polarity: Do not connect the sensor with reverse polarity; it has polarity protection but this should not be tested unnecessarily.

• Calibrate In Air: Regularly calibrate the sensor in the air to maintain accuracy.,
• Use With Compatible Boards: Ensure compatibility with boards like Arduino Uno, ESP32, Raspberry Pi, etc.,
• Check Voltage Requirements: Operate within the 3.3V to 5.5V input voltage range.

• Description: The sensor can operate in a humidity range from 0 to 100% RH.

• Description: The sensor can detect oxygen concentrations from 0 to 30% Vol.

• Description: The sensor should be operated within a voltage range of 3.3 to 5.5 volts.

• Description: Use the provided Gravity-4pin I2C Cable to connect the sensor to compatible microcontrollers via the I2C interface.
