This 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, high sensitivity, etc., and the service life is as long as two years. The sensor has 32 modifiable I2C addresses, an integrated temperature compensation algorithm, and a threshold alarm function, It has good compatibility with mainstream main control devices such as ArduinoESP32, and Raspberry Pi. The easy-to-use Gravity interface, coupled with our sample code, can quickly build an ozone concentration detector.

DFRobot has introduced 12 gas detection sensors in this series, COO2NH3H2SNO2HCLH2PH3SO2O3CL2HF, which are used in exactly the same way and data format, so you can combine them according to your needs.
