PM2.5 is one of the most discussed words in recent years. As the haze becomes increasingly serious, it has had a non-negligible impact on human health. People are concerned about the environment around them. Air quality is also increasingly valued. Recently, a design team from Canada developed a wearable device "TZOA" that can monitor air quality and ultraviolet intensity. Its appearance is small and exquisite, with a round plastic sleeve holding a metal triangle piece, which looks more like a unique pieceJewelry can be hung on clothes, handbags or bicycles, or even worn as a necklace and hung on the chest.
TZOA has an optical particle calculation function. The triangular metal piece has a dedicated optical sensor, which can help the device identify suspended particles in the air and calculate the surrounding PM2.5 and PM10de content. , which can update monitoring data according to real-time changes in the air and transmit the results to the mobile phone or tablet connected to it. UV intensity, temperature, humidity and light levels are similarly collected via sensors. It can also display the results in the form of chart data. If the data is not ideal, it will push a reminder message to the user in time. You can also learn data about other places in the city through the app, allowing you to avoid areas with serious air pollution in time.
