This full-scale oxygen sensor employs the original AO2 CiTiceL oxygen sensor probe and features a measurement range of 0-100%Vol and I2C digital output, which can be adapted to application scenarios including oxygen generators, automobile exhaust, and air-fuel ratio detection. The DFRobot oxygen sensor has a built-in calibration algorithm on the signal board that can quickly perform single-point or double-point calibration so as to accurately measure the oxygen concentration in the environment. Based on the principle of electrochemistry, the sensor probe comes with strong anti-interference ability, high stability and sensitivity, and up to two years of service life. It is compatible with mainstream controllers such as Arduino, ESP32, Raspberry Pi, etc. Besides, the sensor is designed with an easy-to-use Gravity interface, and with our sample codes, you can quickly build an oxygen detector.

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
