The DFRobot Gravity Oxygen Sensor employs an electrochemical cell to measure ambient oxygen levels. This sensing principle provides high selectivity for O2 molecules, resulting in stable readings with minimal cross-sensitivity to other common gases. The onboard signal conditioning circuitry delivers a clean, digital I2C signal, simplifying integration compared to analog sensors that require additional ADC channels.
The module is designed for durability in various environments, operating across a full 0-100% relative humidity range. Its compact form factor and included Gravity connector system allow for rapid deployment in portable air quality monitors, environmental data loggers, and fixed installation scenarios. The sensor is pre-calibrated in air, and its typical operational lifespan is two years under normal atmospheric conditions.
