Gravity - O3 ozone sensor - I2C / UART - factory calibrated - DFRobot SEN0472
An advanced sensor from DFRobot, it allows you to measure the concentration of ozone O3 in your environment. It is compatible with a wide range of microcontrollers, including Arduino, Raspberry Pi or ESP32. The module has a factory calibrated probe that allows for fast and precise measurement. It supports three output interfaces: analog, I2C and UART. The ozone detection range is from 0 ppm to 10 ppm. In addition, the module has strong anti-interference properties, has very good sensitivity and high measurement stability.

Gravity - sensor for detecting ozone in the environment.
Product compatible with Arduino, ESP32, Raspberry Pi
The manufacturer has prepared a detailed user guide, which includes, among other things, connection instructions and sample program code.
Botland is an official distributor of DFRobot open-source hardware. Every roboticist and practitioner of emerging technology has heard at least once of DFRobot solutions, built above all around Arduino. Our range holds original DFRobot products only.
The sensors have the same data format so they can work in parallel.
A series of pre-calibrated sensors from DFRobot
The manufacturer DFRobot has developed a series consisting of up to 12 sensors that have been factory calibrated. These modules enable the detection of the most common gases in the environment. Among them we can find sensors such as CO, O2, NH3, H2S, NO2, HCL, H2, PH3, SO2, O3, CL2, HF.
In addition, the sensors in this series operate in the same way and have the same data format, so they can work in parallel.
How ozone affects life on earth
We often wonder if ozone is a variety of oxygen? How is ozone formed? Does ozone kill insects and bugs? We hurry with the answer.
Ozone is a triatomic variety of oxygen. It is a strong oxidizing agent and reacts very easily with chemicals. It has useful properties (e.g. when it absorbs ultraviolet radiation or disinfects water) and toxic properties when it is too close to the Earth - it destroys vegetation, damages lung tissues. It is most often found in smog.
