Gravity: Electrochemical Oxygen Sensor (0-100%Vol) - I2C
This full-scale oxygen sensor uses an original AO2 CiTiceL electrochemical probe to measure oxygen concentrations from 0–100%Vol via I2C digital output. A built-in calibration algorithm on the signal board supports single-point or double-point calibration for accurate readings in demanding environments.
The electrochemical sensing principle provides strong anti-interference ability, high stability, and up to two years of service life. Compatible with Arduino, ESP32, Raspberry Pi, and other mainstream controllers, the sensor uses DFRobot's Gravity interface for quick plug-and-play connections.
