Detect Ozone centration (O3) in the environment

The Gravity Ozone O3 is a board featuring an I2C Ozone Sensor (0-10ppm) using electrochemical principles. This sensor board is convenient to measure the ambient O3 concentration accurately. The sensor features a high anti-interference ability, high stablility and high sensitivity.
This sensor is arduino-compatible (can also be used with 3.3V logic microcontroler) can be used for portable device, air quality monitoring, disinfection cabinets and smart home.

This compact ozone sensor supports I2C output, it is compatible with many development boards like Arduino Uno, ESP32, MicroPython, Raspberry Pi, etc. Its resolution can reach to 10ppb (parts per billion).

It supports wide range input voltage: 3.3V to 5.5V and offer a good lifetime of 2 years in normal usage condition.

With simple Gravity interface and practical sample code, you can build your own ozone concentration monitor easily and conveniently.


  • Measuring ozone concentration in the environment
  • Supports Gravity 4-Pin Interface
  • Accurate Digital Output

About Ozone:

Ozone is a gas with a fish-like smell. It has a strong stimulating effect on the human body. The ozone is mainly produced by the photochemical reaction NOx, VOCs, and other pollutants (human activity based gaz emission). Under sunny conditions and strong ultraviolet radiation, NO2 etc. undergo photolysis to produce nitric oxide and triplet oxygen atoms, and triplet oxygen atoms react with oxygen to generate ozone.

So, when air pollution increase then the Ozone increase. The ozone is also one of the main air polluant (and is the result of other kinds of air polluants).
