Gravity O2 Oxygen Sensor 0-25%Vol I2C and UART

The Gravity O2 Oxygen Sensor from DFRobot is a precisely calibrated sensor that is specifically designed for measuring the concentration of oxygen in the air. With a measuring range of 0 to 25% Vol and a resolution of 0.1% Vol, this sensor is ideal for a variety of applications, from environmental monitoring to industrial processes. It supports analog, I2C, and UART output modes, enabling flexible integration into existing systems. The electrochemical measurement method guarantees high stability and sensitivity while being less susceptible to interference. Thanks to its easy handling and compatibility with common microcontrollers such as Arduino, ESP32, and Raspberry Pi, the sensor can quickly be integrated into projects. The sensor's lifespan is more than two years, allowing long-term use without frequent replacement.
