When Samsung released the Samsung Galaxy S 5, one of the pieces of hardware they included in the device to try to differentiate it from the market was heart rate sensor. This was part of a larger effort by Samsung to capitalize on health and fitness features as selling points for mobile devices. Continuing down this path, Samsung’s next step is to include an ultrviolet (UV) sensor in the forthcoming Samsung Galaxy Note 4.
The sensor will be used to measure UV radiation by pointing the back of the device towards the sun so the sensor can take its readings. The information will then be passed on to the Samsung S Health app which will display information and helpful hints about UV exposure to users.
Samsung will convert the UV readings into one of five UV index levels – low, moderate, high, very high, and extreme. The levels are defined as:
UV Index 0-2 (Low): UV Index reading of 0 to 2 means low danger from the sun’s UV rays for the average person.
UV Index 3-5 (Moderate): A UV Index reading of 3 to 5 means moderate risk of harm from unprotected sun exposure.
UV Index 6-7 (High): A UV Index reading of 6 to 7 means high risk of harm from unprotected sun exposure. Protection against skin and eye damage is needed.
UV Index 8-10 (Very High): A UV Index reading of 8 to 10 means very high risk of harm from unprotected sum exposure. Take extra precautions because unprotected skin and eyes will be damaged and can burn quickly.
UV Index 11+ (Extreme): A UV Index reading of 11 or more means extreme risk of harm from unprotected sun exposure. Take all precautions because unprotected skin and eyes can burn in minutes.
Samsung also plans to include some trivia about UV radiation and the dangers it creates for users in the S Health app. The goal of the readings and information is to help users protect themselves by preventing unnecessary damage to their skin and reducing the odds of skin cancer.
