Abstract
Electrical resistivity is a fundamental parameter of metals or electrical conductors. Since resistivity is a function of temperature, in order to completely understand the behaviour of metals, a temperature dependent theoretical model is needed. A model based on physics principles has recently been developed to obtain an equation that relates electrical resistivity to temperature. According to the experimental evidence it is shown that RTDs gives a linear relationship of temperature and by the help of equation we can understand the behaviour of resistivity with temperature. Recently, now a days demand of temperature measuring mobile devices are increasing day by day therefore a new precision method is introduced based on thermistor sensor to accurately measure the temperature of body in extremely difficult condition. Human body temperature can be measured using a thermistor sensor.
