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 environmentCan 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 Arduino, ESP32, 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, CO, O2, NH3, H2S, NO2, HCL, H2, PH3, SO2, O3, CL2, and HF, which are used in exactly the same way and data format, so you can combine them according to your needs.

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
