Gravity: 0-100% Vol Electrochemical Oxygen (O2) Sensor | Industrial-Grade Electrochemical Module | I2C Output | High-Precision Monitoring for Medical Concentrators | for Arduino, ESP32, Raspberry Pi

Be the first to review this product...
  • [0-100% VOL WIDE RANGE DETECTION] Unlike standard 25% environmental sensors, this industrial-grade module supports a full 0-100% Vol range. It is purpose-built for high-concentration O2 monitoring in medical oxygen concentrators, diving gear, and specialized lab prototypes.
  • [I2C DIGITAL OUTPUT & QUICK-CALIBRATION] Integrated with high-performance signal processing, this sensor provides direct digital data via I2C, eliminating the need for complex analog circuit design. It features built-in calibration algorithms that support quick single-point or double-point calibration, ensuring long-term accuracy and stability for professional IoT deployments.
  • [PROTOTYPING & INDUSTRIAL RELIABILITY] Optimized for commercial R&D and B2B procurement, this sensor uses the original AO2 CiTiceL probe for superior anti-interference and stability. It operates reliably in challenging environments with pressures from 0.5 to 2.0 Bar, making it a dependable choice for industrial-grade integration.
  • [PLUG-AND-PLAY GRAVITY ECOSYSTEM] Equipped with the standard Gravity 4-Pin interface, it allows for solderless connection to the controller. Fully compatible with Arduino UNO, ESP32, and Raspberry Pi, with libraries provided.
  • [VERSATILE PROFESSIONAL APPLICATIONS] An essential component for STEM educators, IoT engineers, and medical device developers. Perfect for building oxygen alarms in confined spaces, plant photosynthesis monitors, and combustion efficiency analysis systems.
