Question: You are asked to design a temperature sensor that converts temperature change into voltage. You are required to use an RTD, within a W.

You are asked to design a temperature sensor that converts temperature change into voltage. You are required to use an RTD, within a W. Bridge, and an appropriate amplifier. The output voltage should start from 1 V for minimum temperature, the other end will be left for you for now. In future, that end should be trimmed to standard value. Your temperature range is 20 C to 70 c. Choose an RDT ( PT100, PT1000, PTS0. etc) and use it, such that your circuit would give 1 volt output when the temperature is lowest. You should explain what is the output of the circuit for at least five values along the whole span of temperatures, what is the range, and what is the sensitivity of the measurement device you designed. Explain the details of your amplifier, the choice of its type, the choice of ycc, problems could be faced in realizing this device, and schematic of your circuit. If you are using a standard battery for your circuit (4,5 V), choose a battery online, and find how long it will work before you need to replace it?
