A transducer is the moniker usually given any device that is
typically used to monitor the physical activity in a given system.
An IR resistor bolometer resolves heat to electrical output.
A condenser microphone resolves air motion into electrical activity
A strain gauge integrated circuit device, which is a small system
unto itself, but operates as a transducer. It resolves pressure into
an electrical signal.
An LVDT position sensor resolves physical position into an impedance
An IR Light sensitive receiver packaged just like the IR transmitter
LED. They resolve digitally pulsed IR light into binary electrical
A CCD array is an entire array of tiny transducers that get called
"pixel elements" by us. They resolve optically corrected and focused
color information into 2-D imagery.
