- [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 environments—no 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.
- [VERSATILE IoT APPLICATIONS] The ultimate choice for DIY makers, STEM educators, and engineering prototypes. Ideal for monitoring air quality in confined spaces, underground garages, smart greenhouses, mushroom cultivation, and building safety alarm systems. (Note: Designed for ambient air monitoring; not suitable for medical or 100% pure oxygen applications).
