    Gravity: Factory Calibrated O2 Sensor Module | 0-25% Vol Electrochemical Oxygen Gas Detector | I2C UART Analog Output | Built-in Temp Compensation | for Arduino, ESP32, Raspberry Pi

    • [FACTORY CALIBRATED & PLUG-AND-PLAY] Save development time with the pre-calibrated probe. Unlike standard O2 sensors requiring complex gas calibration, this module is ready for immediate use, providing high-accuracy oxygen concentration data out of the box to accelerate IoT project deployment.
    • [BUILT-IN TEMPERATURE COMPENSATION] Electrochemical sensors often face environmental shifts. The onboard temperature compensation algorithm minimizes data drift, ensuring stable and reliable oxygen concentration readings even under fluctuating ambient temperatures.
    • [I2C, UART & ANALOG OUTPUT] Designed for system integration, featuring a 37x32mm signal conversion board and O2 sensor probe. This module supports I2C, UART, and Analog voltage outputs. Flexible interface options and 32 switchable I2C addresses simplify connections with Arduino, ESP32, or Raspberry Pi controllers.
    • [HIGH STABILITY & Long Life] Equipped with a high-performance electrochemical probe, this module offers strong anti-interference and a lifespan exceeding two years in normal air. Features 3.3V-5.5V wide voltage input and reverse polarity protection for quick prototyping.
    • [VERSATILE ENTERPRISE APPLICATIONS] An essential environmental monitoring component for IoT engineers and hardware developers. Ideal for deploying safety alarms in confined spaces, smart greenhouse climate control, and rapid scientific prototyping.
