SEN0321 Gravity I2C Ozone Sensor (0-10ppm)

DFRobot SEN0321 Gravity I²C Ozone Sensor (0-10ppm) is based on electrochemical principles and can measure the ambient O3 concentration accurately and conveniently. With high anti-interference ability, high stability, and high sensitivity, this Arduino-compatible ozone sensor can be widely applied to fields like portable devices, air quality monitoring devices, disinfection cabinets, and smart homes. This compact DFRobot ozone sensor supports I²C output and is compatible with many mainboards like Arduino Uno, esp32, Raspberry Pi, and more. Its resolution can reach to 10ppb. It supports a wide range of input voltage: 3.3V to 5.5V. The lifetime is also as long as two years. With a simple Gravity interface and practical sample code, the user can build an ozone concentration monitor of their own easily and conveniently.
