Gravity: Factory Calibrated Electrochemical Oxygen (O2) Sensor
The Gravity: Factory Calibrated Electrochemical Oxygen (O2) Sensor is a high-precision gas sensing solution designed for accurate and reliable measurement of oxygen concentration in various environments. Built on an advanced electrochemical sensing principle, the probe is factory calibrated, enabling fast deployment and precise readings without complex calibration procedures. Supporting three output modes – Analog, I2C and UART, the sensor offers excellent flexibility and seamless integration with popular development platforms such as Arduino, ESP32 and Raspberry Pi. Its strong anti-interference capability, high sensitivity and exceptional stability make it suitable for long-term monitoring applications.
Featuring an integrated temperature compensation algorithm, adjustable alarm threshold function and support for 32 configurable I2C addresses, this O2 sensor is engineered for intelligent and scalable system design. With a service life of up to two years, it is ideal for portable devices, air quality monitoring systems, industrial safety, mines, warehouses and enclosed spaces with poor air circulation. The Gravity plug-and-play interface, along with comprehensive sample code, allows developers to quickly build a reliable oxygen concentration detection system. Additionally, this sensor is part of DFRobots Gravity electrochemical gas sensor series, which includes 12 different gas types that share the same interface and data format, enabling easy multi-gas expansion.
