Summary

• The ozone sensor launched by DFRobot adopts the principle of electrochemistry and has been calibrated before leaving the factory, which can accurately measure the ozone concentration in the environment.
  
• And it has the characteristics of anti-interference, high stability and high sensitivity.
  
• The resolution can reach 10ppb
  
• support 3.3~5.5V wide voltage input
  
• use I2C output
  
• compatible with mainstream devices such as Arduino, ESP32, Raspberry Pi, etc
  
• the service life in the air is up to two years
  

Installation

There are two methods for using this library:

1. Open Arduino IDE, search for "DFRobot_OzoneSensor" on the status bar in Tools ->Manager Libraries and install the library.
   
2. Download the library file before use, paste it into \Arduino\libraries directory, then open the examples folder and run the demo in the folder.
