Gravity: Electrochemical Oxygen / O2 Sensor (0-25%Vol, I2C)
6.900,00 EGP
This Oxygen / O2 Sensor is based on electrochemical principles and can measure ambient oxygen concentration accurately and conveniently. With high anti-interference ability, high stability, and high sensitivity, this Arduino-compatible oxygen sensor can be widely applied to portable devices, air quality monitoring systems, and environments such as industries, mines, warehouses, and other spaces where air circulation is limited.
Designed for measuring oxygen levels in ambient air (0–25%Vol), this sensor is ideal for applications such as environmental monitoring, safety detection in enclosed spaces, and oxygen concentration analysis.
This compact DFRobot oxygen sensor supports I2C output and can be calibrated in air for accurate measurement. It is compatible with many mainboards like Arduino Uno, ESP32, and Raspberry Pi. Its measurement range is 0~25%Vol, with a resolution of up to 0.15%Vol. It supports a wide input voltage range from 3.3V to 5.5V.
With a service life of over 2 years under normal conditions, along with a simple Gravity interface and practical sample code, users can quickly build their own oxygen concentration monitoring systems.
For optimal accuracy, periodic calibration is recommended depending on the usage environment.
