How much do you really know about the environment that you live in? The air that you breathe? The UV that you are exposed to? Now you can find out with the TZOA, the world\u2019s most advanced Enviro-Tracker. It uses internal sensors to measure air quality, temperature, humidity, atmospheric pressure, ambient light and UV exposure, all in one wearable device. You can connect the TZOA to your smartphone to view your readings and receive recommendations. By using the TZOA your data will be collected to create a crowd sourced map of environmental data in real-time so that you can find the freshest air for a jog or the best weather for a picnic.
