Gravity: I2C Electrochemical Oxygen (O2) Sensor Module | 0-25% Vol Range | Plug & Play Digital Gas Detector | No Soldering | 3.3V-5.5V for Arduino, ESP32, Raspberry Pi | IoT & Air Quality Monitoring

[INSTANT DIGITAL READINGS VIA I2C] Stop wrestling with complex ADC formulas! Unlike traditional analog sensors, this O2 module features a built-in signal conditioning chip that outputs precise oxygen concentration directly via I2C interface. Saves hours of coding and eliminates voltage-drop errors, making the project development effortless.. [PLUG & PLAY, NO SOLDERING REQUIRED] Designed with a standard Gravity 4-pin interface and including the connecting cable, users can say goodbye to messy wiring. Supports a 3.3V ~ 5.5V wide voltage input, ensuring compatibility with Arduino Uno ESP32, and Raspberry Pi without needing level converters.

. [HIGH PRECISION & QUICK CALIBRATION] Accurately measures ambient oxygen levels (0-25% Vol range) with a high 0.15 % resolution and fast response time (15s). Worried about complex setups? We provide ready-to-use sample code that allows for a quick air calibration process in natural environmentsno expensive calibration gases needed.. [2-YEAR LIFESPAN & HIGH STABILITY] Powered by an electrochemical probe, it offers exceptional resistance to cross-gas interference and ultra-low drift (<2% per month). Built to operate reliably in harsh environments (-20~50°C), delivering a long service life of over 2 years in normal air conditions.
