Description

The Oxygen Sensor is an electrochemical device that can accurately and conveniently measure the concentration of oxygen in the air. It has high anti-interference ability, stability, and sensitivity and can be used in a variety of applications, including portable devices, air quality monitoring devices, and in industries, mines, warehouses, and other spaces where air circulation is limited.

This compact oxygen sensor is compatible with the Arduino Uno, esp32, Raspberry Pi, and other mainboards and supports I2C output. It can be calibrated in the air and has a measurement range of 0-25% Vol with a resolution of 0.15% Vol. It is compatible with a wide range of input voltages (3.3V to 5.5V) and has a long lifespan of up to 2 years. With its simple Gravity interface and practical sample code, you can easily build your own oxygen concentration monitor.
