Introduction
Statement of Purpose →
For our project we wish to design gloves that are smart enough to let you know when your temperature and/or heartbeat reaches dangerous levels. With the use of a pulse sensor and temperature sensor, we will be able to regulate a user’s vitals while subject to various temperatures and exercise levels. If time permits, we will also use conductive thread to implement a pause/play button to help control music being played by a nearby device.
Background Research →
The cold Illinois whether is what inspired us to create this project. With implementation of these gloves, the elderly, young children, and any other user can feel protected from the cold whether while outside for extended periods of time. According to the National Weather Service, a person can be exposed to temperatures of -18 degrees Fahrenheit for only 30 minutes before resulting in frostbite. As wind chill increases and the temperature is significantly lowered, the length of time one can spend outside before experiencing frostbite can decrease to only 5 minutes. Since we will be measuring the temperature of one's fingertips rather than the ambient temperature, it is important to know what body temperatures result in various stages of hypothermia. According to the Department of Public Health and Human Services, mild hypothermia begins when one's temperature drops to 95 degrees Fahrenheit, moderate hypothermia begins at 90 degrees Fahrenheit, and severe hypothermia begins at 82 degrees Fahrenheit. Frostbite, the freezing of tissue, may also occur in cold whether because as blood vessels narrow, our blood flow and oxygen levels are reduced. Our idea could also be extended for use when reaching high altitudes with extremely cold temperatures; for example, mountain climbers. Hopefully, we will be able to add a few other additions to make the gloves even smarter, including the ability to control music.

System Overview →
The pulse sensor will be implemented on the Smart Glove near the inside of the wrist, so that a pulse can be monitored. The values of the changing pulse will then be sent to the arduino board. Similarly, the temperature sensor will also be implemented on the Smart Glove, most likely near the fingertips, in order to monitor one’s body temperature. The temperature values measured from the temperature sensor will also then be sent to the Arduino. Installed on the Arduino will be code that interprets when these values reach critical zones. For example, if one’s heartbeat is greatly increased or decreased to a dangerous level, and/or if one’s temperature reaches a value that is too high or too low to be considered safe the arduino will output a signal. The arduino will control whether or not various LEDs are turned on in order to signal to the user, or anyone around the user, that their vitals are reaching dangerous levels.
