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

Precaution:

1. Do not plug or unplug sensors on the module.
2. 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.
3. 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.
4. The module cannot be used in an environment containing corrosive gas for a long time. Corrosive gas will damage the sensor.
5. The module must not be subjected to excessive shock or vibration.
6. 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.
7. The white waterproof and breathable membrane of the sensor on the module is strictly forbidden to open, otherwise it is regarded as artificial damage.
8. Do not install the module in a strong convection air environment.
9. Do not place the module in high-concentration organic gas for a long time. Long-term storage will cause the sensor zero point to drift and recover slowly.

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. This sensor has an onboard conditioning circuit for amplifying the output signal.

Healthy living starts with healthy air! As the most basic part of life, air is attracting more and more attention these years, for example, PM2.5, smog, etc. Keeping an eye on the quality of the air we breathe is becoming quite important.

This Air Quality Monitor introduced by DFRobot provides you with the measurements of PM10, PM2.5, and PM1.0 as well as temperature and humidity. It works well with devices like Arduino, STM32.Based on the principle of laser scattering, this sensor continuously collects and calculates the number of suspended particles of various sizes in the air per unit volume, which is particle concentration distribution, and then converts to mass concentration. At the same time, a temperature & humidity integrated sensing chip is embedded in the module for accurately detecting the temperature and humidity.
