transeducers

A sensor sences signals.For eg: any LDR(light dependent resistor) can sense changes in light intensity and respond accordingly.
A transducer converts one form of energy to another.Eg: a microphone converts sound signals to electric signals.
A transmitter transmits information from a source like an amplifier stage etc.
In many cases a transducer acts like a sensor.

hi
you can find more about sensors in this book:


you can download it!

sensor transducer stage

sensors: that convert certain power from form to electrcial form, like mic (speach to electrical signal), or themostate (tempertature to electrcial signal), infrared, altrasonic ...
Transeducers: that produce power form from electrical form, like speaker, heater, ....
Transmitter: that transfere electrical signal (over electromagnetic wave (antenna) or electrical waves (wires -telephone-) from point (Treanmitter) to another point (Reciever)
Transmitter consists of any components (encoder-modulator-RF stage(antenna))
