With high anti-interference ability, high stability, and high sensitivity, this Arduino-compatible ozone sensor can be widely applied to fields like portable devices, air quality monitoring devices, disinfection cabinets, and smart homes.
This compact ozone sensor supports I2C output, it is compatible with many mainboards like Arduino Uno, esp32, Raspberry Pi, and so on. Its resolution can reach 10ppb. It supports a wide range of input voltage: 3.3V to 5.5V. Moreover, the lifetime is as long as 2 years. With a simple Gravity interface and practical sample code, you can build your own ozone concentration monitor easily and conveniently.
Precaution:
- Do not plug or unplug sensors on the module.
- It is forbidden to change or shift the installation state of electronic components. The module avoids contact with organic solvents (including silicone and other adhesives), coatings, pharmaceuticals, oils and high concentrations of gases.
- The module cannot be completely encapsulated with resin material, and it cannot be immersed in an oxygen-free environment, otherwise the performance of the sensor will be damaged.
- The module cannot be used in an environment containing corrosive gas for a long time. Corrosive gas will damage the sensor.
- The module must not be subjected to excessive shock or vibration.
- The module needs to be warmed up for about 24-48 hours after it is powered on for the first time. After the module is fully stable, it will be tested normally.
- The white waterproof and breathable membrane of the sensor on the module is strictly forbidden to open, otherwise it is regarded as artificial damage.
- Do not install the module in a strong convection air environment.

The greenhouse Effect” is melting the Earth’s ice core every minute and creating dangerous icebergs. By knowing the exact concentration of CO2(Carbon Dioxide), we can do something to reduce the CO2 and to protect our Earth. Here is the Arduino-based CO2 sensor designed by DFRobot’s lovely engineer. This is the first CO2 sensor in the Arduino market. The output voltage of the module falls as the concentration of CO2 increases. The potentiometer onboard is designed to set the threshold of voltage. As long as the CO2 concentration is high enough (the voltage is lower than the threshold), a digital signal (ON/OFF) will be released.
It has an MG-811 sensor module which is highly sensitive to CO2 and less sensitive to alcohol and CO, low humidity & temperature dependency. The onboard heating circuit brings the best temperature for the sensor to function. Internal power boosting to 6V for heating sensor best performance.
