Overview
The Gravity: I2C Oxygen Sensor is based on electrochemical principles and it can measure the ambient O2 concentration accurately and conveniently. With high anti-interference ability, high stablility and high sensitivity, this arduino-compatible oxygen sensor can be widely applied to fields like portable device, air quality monitoring device, and industries, mines, warehouses and other spaces where air is not easy to circulate.
This compact dfrobot oxygen sensor supports I2C output, it can be calibrated in the air, can accurately measure the oxygen concentration in the environmentit. It is compatible with many mainboards like Arduino Uno, esp32, Raspberry 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.

Arduino is excited to announce a strategic new partnership with RS/OKdo, a prominent leader in the distribution of industrial and electronic equipment. This collaboration marks a significant step forward in bringing Arduino’s technology closer to China’s thriving maker community and enterprise sector, offering enhanced local support and access to original Arduino boards and resources. Empowering a growing community in China With over 2.7 million active users of the Arduino IDE in China, one of our top priorities is to deliver an even better experience for the Arduino Community. This partnership with RS/OKdo means users will enjoy more local language content, technical support, competitive pricing, and most importantly, easier access to official Arduino products. Official Arduino boards, certified for China As part of this initiative, a range of classic and most popular Arduino boards has been specifically manufactured for the Chinese market. These boards are exactly the same as Arduino’s global versions of the same products, produced in Italy to Arduino’s highest standards, tested rigorously for quality and performance. Each product , although certified exclusively for the Chinese market, matches the same technical specifications and high-quality benchmarks as those sold worldwide. The boards are available only through RS/OKdo and Arduino/OKdo’s authorized sub-distributors. They have unique Arduino MPNs but with a _CN suffix: Arduino UNO R4 Wifi (ABX00087_CN) Arduino UNO R4 Minima (ABX00080_CN) Arduino UNO R3 (A000066_CN) Arduino Nano ESP32 with (ABX00083_CN) and without (ABX00092_CN) headers Arduino Nano R3 (A000005_CN) Arduino Mega 2560 (A000067_CN) Arduino DUE (A000062_CN) Front & back of official UNO R4 WiFi - SKU ABX00087_CN Front & back of official UNO R3 - SKU A000066_CN Expanding local support for enterprise transformation In addition to supporting makers, RS/OKdo will provide enhanced
