We will make with the resistive temperature sensor PT100, aWheatstone bridge, ainstrumentation amplifier AD620, and an analog digital converterADC0804 inproteus, do the temperature range measurement, the range of thisPT100 sensor isfrom 0°C to 300°C, they must also calculate what their limitvoltage is going to be and thereference that they will occupy for the ADC if it is necessary tooccupy it.Needed:• Assembly of the Wheatstone bridge circuit and AD620.• Assembly of the ADC0804 circuit connecting the output of theAD620 to the input of the ADC.• Calculation of voltage divider for VREF (if necessary).• Screenshots of the simulation testing the circuits
