Integrated Circuit Temperature Sensor
Integrated Circuit Temperature Sensor. An IC Temperature Sensor is a two terminal integrated circuit temperature transducer that produces an output current proportional to absolute temperature. In previous projects with temperature sensor circuits, we built the circuit and then got a readout on the computer that we programmed the circuit with.

To use a temperature sensor in a control or compensation circuit, the detection circuit must provide an output in a usable format.
Applications, advantages and disadvantages of the IC based.
A temperature sensor detects the temperature of an object or of its environment and converts the reading into an electrical signal. As thermistors and RTDs output a variable resistance, this makes it straightforward to integrate them into an analog control or compensation circuit. Local temperature sensors sense the temperature on printed circuit boards or the ambient air around it.
