A temperature detector circuit in Proteus is a virtual circuit that can be used to simulate the behavior of
a real-world temperature sensor circuit. The circuit typically consists of a temperature sensor, a resistor,
and an amplifier. The temperature sensor is used to measure the temperature, and the resistor is used
to form a voltage divider with the sensor. The amplifier is used to amplify the output voltage of the
voltage divider so that it can be easily measured or displayed.The following is a simple example of a
temperature detector circuit in ProteusThe temperature sensor is an LM35 temperature sensor.The
resistor is a 10kΩ resistor.The amplifier is an LM324 operational amplifier.The LM35 temperature sensor
has an output voltage that is linearly proportional to the temperature. The output voltage of the sensor
is 10mV per degree Celsius. The 10kΩ resistor is used to form a voltage divider with the sensor. The
output voltage of the voltage divider is 100mV per degree Celsius. The LM324 operational amplifier is
used to amplify the output voltage of the voltage divider by a factor of 10. This means that the output
voltage of the amplifier is 1V per degree Celsius.The temperature detector circuit can be used to
simulate the behavior of a real-world temperature sensor circuit. The circuit can be used to measure the
temperature of a object, or it can be used to control the temperature of a device.
