Gravity: Factory Calibrated Electrochemical Ozone Sensor (0-10 ppm, I2C & UART) Category_Educational the driver is in serialThis is a sensor that detects ozone concentration and supports three output modes: analog, I2C, and UART. The probe has been calibrated at the factory, which can quickly and accurately measure the concentration of ozone in the environment. Can be widely used in industrial and environmental protection fields for ozone detection. The probe adopts the electrochemical principle, has the characteristics of strong anti interference ability, high stability,
