Here is the circuit diagram of an electronics thermometer using op-amp 741 IC and a silicon diode having a range of -20oC to 125oC. Various types of temperature measuring and controlling circuits either using a microcontroller or discrete component are already posted on bestengineeringprojects.com. Circuit Diagram of Electric Thermometer Using OP-AMP 741 The entire circuit of the electric thermometer is built around two op-amp 741 IC, a silicon diode, and a few passive components, where silicon diode D1 is used as a temperature sensor. The diode 4148 has a voltage…
