Simple Diagram Of Thermistor. However due to the nonlinear relationship between resistance and temperature some approximations are utilized to design practical system. Tl082 or any other general purpose opamps can also be used.
Operational details of electronic thermostat. How thermostats work. The beauty of tl072 and tl082 is that there are two opamps in one package.
Since the thermistor is a variable resistor well need to measure the resistance before we can calculate the temperature.
Simple diagram of thermistor. The circuit diagram of thermistor uses the rectangular block which has a diagonal line on it. Thermistors are also available with metal or plastic cage style element covers for air temperature measurement. Automatic temperature control using 8085 microprocessor.
