With high anti-interference ability, high stability, and high sensitivity, this Arduino-compatible oxygen sensor can be widely applied to fields like portable devices, air quality monitoring devices, and industries, mines, warehouses, and other spaces where the air is not easy to circulate.\n  \u003c\/p\u003e\n\n  \u003cp\u003e\n    This compact 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 Uno, esp32, Raspberry Pi, and so on. Its effective range is 0~25%Vol, and resolution can reach to 0.15%Vol. It supports a wide range of input voltage: 3.3V to 5.5V. Moreover, the lifetime is as long as 2 years. With a simple Gravity interface and practical sample code, you can build your own oxygen concentration monitor easily and conveniently.\n  \u003c\/p\u003e\n\n  \u003cdiv class=\"note\"\u003e\n    \u003cstrong\u003eImportant:\u003c\/strong\u003e Use the official DFRobot links below for wiring, sample code, downloads, and the latest setup notes for this SKU.\n  \u003c\/div\u003e\n\n  \u003ch3\u003eWhy you'll love it\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003eHigh sensitivity\u003c\/li\u003e\n    \u003cli\u003eI2C Interface\u003c\/li\u003e\n    \u003cli\u003eCompatible with both 3.3V and 5V micro-controllers\u003c\/li\u003e\n    \u003cli\u003ePolarity protection\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eDetection of Gas:\u003c\/strong\u003e oxygen\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOperating Voltage:\u003c\/strong\u003e 3.3 to 5.5V DC\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eWhat you can build\u003c\/h3\u003e\n  \u003cp\u003e\n    This part fits monitoring, measurement, logging, alarms, and automation builds.
