Wireless skin temperature sensing patch

Temperature is very important parameter of the human body. By measuring the body temperature early diagnoses of the simple diseases such as fever are possible. In patient suffering from a fever the body temperature has to be measured again and again which is irritating work for the nurses in the hospital. So it is advantageous to make a device which can measure the skin temperature for 24 hours and thus nurses are used for more critical work. This paper focused on measuring of skin temperature of the human body wirelessly for 24 hour. The system used the 434 MHz ISM band frequency to send the signal wirelessly to the receiver. Classic OOK communication is used.
