This project presents a well defined method to design an electronic room thermometer using µA 7 41 operational amplifier (op-amp). The main building block of the design is the µA741 op-amp and the 'brain' part of the design is the LM3911 IC temperature sensor. We have designed a device that exhibits very good performance, that is, comparable to the mercury thermometer in measuring the temperature of a room.
