The energy radiated by the sun comes in a wide range of wavelengths, most of which are not visible to our eyes. Sunlight is the main source of ultraviolet (UV) rays. The Earth’s atmosphere prevents most of the Sun’s UV radiation from penetrating through the atmosphere. The small amount that gets through has both positive and negative effects. While UV ray has some beneficial effects on our health, over-exposure to this ray is a major risk factor for most skin cancers.
Smart wearables to monitor UV radiation are few and far between. Depending on the brand, these UV monitors can be worn in various ways. Some of them clip on to your clothes, some come in the form of wristbands and some have an adhesive that sticks directly to your skin. We’ve made a list of 5 UV wearables to keep you safe from sunlight.
QSun is a wearable that detects UV exposure and displays UV index using its five LED displays. When you give it a shake, it’ll show your UV index. That’s the measurement of how powerful UV radiation beaming from the sun is. The iOS and Android-friendly app allows you to keep track of how long you have been out in the sun before you start to burn. It will vibrate when you’ve been in the sun for too long. The AI in the device takes skin type into consideration as well, to help determine the time you should spend out in the sun. If you apply some sunscreen, two shakes on the QSun will let it know and it’ll take that into consideration while you’re catching some rays. The device also has step count feature which it can pull from Apple Health and Google Fit to let you know how much of your daily activity was spent in safe UV exposure. After a successful Kickstarter campaign, QSun is now available to buy.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
