So far we have learned about a couple of physical sensors, including a thermistor, diode temperature sensor, transistor temperature sensor, thermistor, strain gauge, and more. For practical applications, the voltage signals generated from these sensors must be conditioned and appropriately amplified. This task is usually achieved by an operational amplifier, more commonly referred to as an op-amp, which we briefly used in our Chap. 3 laboratory.
