Gravity: I2C Ozone Sensor (0-10ppm)
Module with an ozone detection sensor that performs measurements in the range of up to 10 ppm with a resolution of 0.01 ppm.
Overview
Gravity: I2C Ozone Sensor (0-10ppm) is based on electrochemical principles and it can measure the ambient O3 concentration accurately and conveniently. With high anti-interference ability, high stablility and high sensitivity, this arduino-compatible ozone sensor can be widely applied to fields like portable device, air quality monitoring device, disinfection cabinets and smart home.
This compact dfrobot ozone sensor supports I2C output, it is compatible with many mainboards like Arduino Uno, esp32, Raspberry Pi and so on. Its resolution can reach to 10ppb. It supports wide range input voltage: 3.3V to 5.5V.
Moreover, the lifetime is as long as 2 years. With simple Gravity interface and practical sample code, you can build your own ozone concentration monitor easily and conveniently.

Join us for a weekend of special events at the Arduino Store Berlin! Activities will kick off on Thursday, March 9th with teacher training. On Friday, March 10th and Saturday, March 11th, the Arduino team featuring Tenaya Hurst will present some of the latest products, like the Primo and the Otto; in the afternoon, the focus will shift towards the Arduino Uno WiFi and the Arduino Libretto Kit. Everyone (ages 8 and up) is welcome to attend the workshops. Teachers, in particular, will have the opportunity to learn how to present and replicate projects with their students, as well as meet and greet each other during a social brunch on Sunday morning. The Arduino Store is also looking to collaborate with more educators, so don't forget to bring your CV! Registration is now open. The cost of each workshop, which includes an Arduino kit, is €59 +VAT and will be processed at the Berlin store. Please remember your laptop and power cord, and to download the Arduino IDE before attending! Have questions? Do not hesitate to contact events@arduino.org!
