Introduction
This is a small Arduino-compatible ozone sensor module, which can conveniently and accurately measure the concentration of ozone gas in the environment. Can be widely used in portable instruments and meters, air quality monitoring equipment, disinfection cabinets, smart homes and other equipment places.The ozone sensor introduced by DFRobot uses the electrochemical principle and has been calibrated before leaving the factory to accurately measure the ozone concentration in the environment. And has the characteristics of anti-interference, high stability, high sensitivity. The resolution can reach 10ppb, support 3.3 ~ 5.5V wide voltage input, use IIC output, compatible with Arduino, ESP32, Raspberry Pi and other mainstream devices, have good compatibility, the service life in air is up to two years. The easy-to-use Gravity interface, coupled with our sample code, can quickly build your own ozone concentration detector.
Further reading:
Ozone is a gas with a fish-like smell, which has a strong stimulating effect on the human body. Ozone is mainly produced by the photochemical reaction of man-made emissions of NOx, VOCs and other pollutants. 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. As air pollution becomes more severe, ozone has also become one of the main air pollutants.
The National Ambient Air Quality Standards (NAAQS) propose that the limit concentration of ozone that humans can accept within one hour is 260 μg / m3. Coughing, dyspnea, and decreased lung function can be caused by activity in an ozone environment of 320 μg / m3 for 1 hour. Ozone can also participate in the reaction of unsaturated fatty acids, amino groups and other proteins in the organism, which makes people who have been in direct contact with high concentrations of ozone for a long time appear fatigue, cough, chest tightness, chest pain, skin wrinkling, nausea and headache, pulse acceleration, memory loss, vision Drop and other symptoms.
Therefore, in the summer afternoon, if symptoms such as fatigue, chest tightness, and cough appear, the ozone concentration in the air may be too high. Closing doors and windows reduces indoor and outdoor air circulation, and ozone can decompose naturally, which is an effective way to reduce indoor ozone concentration.
*Precautions:
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 the 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.
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.
Do not use hot-melt adhesive or sealant to seal the module above 80°C.
Do not store and use in high concentration alkaline gas for a long time.
