Gravity O3 Ozone Sensor I2C and UART

The Gravity O3 Ozone Sensor from DFRobot is a highly precise, factory-calibrated sensor specifically designed for measuring ozone concentrations in the air. With a measurement range of 0 to 10 ppm and the ability to communicate via analog, I2C, and UART output modes, this sensor provides a versatile solution for environmental monitoring projects, industrial applications, and more. The electrochemical measurement method guarantees high accuracy, stability, and excellent interference resistance. An integrated temperature compensation and threshold alarm function further increases the reliability of the sensor. Thanks to compatibility with popular microcontrollers like Arduino, ESP32, and Raspberry Pi, the sensor can be easily integrated into existing systems.

Features:

• High precision and stability in O3 measurement.
• Supports analog, I2C, and UART output modes.
• Longevity with a life span of over two years.
• Strong anti-interference ability through electrochemical principle.
• Easy integration thanks to Gravity interface and compatibility with Arduino, ESP32, and Raspberry Pi.

Application examples:

• Monitoring air quality in urban areas.
• Used in industrial process control to monitor O3 concentration.
• Environmental monitoring for the detection of ozone pollution.
• Development of portable devices for air quality measurement.
