Op-Amp Temperature Sensing Circuit Design

I would like to explain my project . The project is about designing a temperature sensing circuit using an operational amplifier (Op-Amp) without using any microcontroller. The main idea of the project is to measure the surrounding temperature using a temperature sensor and compare it with a reference temperature that can be adjusted manually using a potentiometer. If the measured temperature exceeds the reference value, the circuit will activate an output, which is an LED indicator. Otherwise, the LED will remain off. This system is useful in applications such as factories, where it is important to monitor temperature to prevent damage to stored goods. In the project, I will: • Design and simulate the circuit using Multisim. • Set the reference temperature (around 24°C) using the potentiometer. • Calculate the corresponding voltage values based on the sensor characteristics. • Test different input conditions (high, medium, low) and compare calculations with simulation results. • Perform a parameter sweep to analyze how the output voltage changes with the variable resistor. The final outcome will be a working circuit where the LED turns on when the temperature exceeds the set threshold. Any one can do it?
