Table of Contents

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.
