We will call this model the real model of the diode. Glass and high temperature solder exemptions applied where applicable, see. You will learn why diode becomes temperature sensor. Turn on the module at normal room temperature about 22 degrees celsius and measure the voltage at the non inverting input of o2 pin 5ic1. Eine ideale exponentielle kennlinie wird daher als gerade abgebildet, eine lineare ohmscher widerstand als logarithmische. A diode is a twoterminal electronic component that conducts current primarily in one direction asymmetric conductance. T 1 is the first temperature at which the circuit is to be simulated, t n is the nth temperature at which the circuit is to be simulated. Measuring temperature with a silicon diode due to the high sensitivity, nearly linear response, and easy availability, we will use a 1n4148 diode for the temperature transducer in our measurements. In the given diagram, it is said that the 1n4148 diode acts as the sensor.
