Description
The Gravity Factory Calibrated Electrochemical Oxygen (O2) Sensor measures environmental oxygen concentration from 0 to 25%Vol with 0.1%Vol resolution. Pre-calibrated at the factory, it supports analog, I2C, and UART output modes with built-in temperature compensation. It is ideally suited to students, makers, and engineers developing air quality monitors, smart farming systems, or safety gear for confined spaces.
Factory-calibrated electrochemical sensing probe
The module utilises an electrochemical probe that offers high sensitivity, strong anti-interference performance, and a lifespan exceeding two years in air. Factory pre-calibration ensures accurate oxygen measurement with a fast response time of 15 seconds or less without the need for manual setup.
Versatile communication and controller compatibility
The sensor supports analog voltage, 0 to 3V UART, and I2C output modes with 32 configurable I2C addresses. Operating from 3.3V to 5.5V DC with a current draw under 5mA, it connects directly to Arduino, ESP32, and Raspberry Pi platforms using the standard Gravity interface.
Integrated temperature compensation and alarms
An onboard temperature compensation algorithm maintains reading accuracy across operating conditions from -20 to 50 degrees Celsius and 15 to 90% relative humidity. It also features an integrated threshold alarm function to trigger notifications when oxygen levels breach preset boundaries.
Standardised multi-gas detection series
This module belongs to a 12-gas electrochemical sensor family that shares identical data formats and wiring conventions for straightforward multi-gas array configurations. The kit includes the oxygen signal conversion board, the electrochemical sensor probe, and a Gravity 4-pin cable.
