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.

Czujniki posiadają ten sam format danych dzięki czemu mogą współpracować równolegle.

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.
