A sensor is a
mechanical device that takes in information and relays it to a human being in a
different location. The rovers on Mars have a large variety of sensors to
measure temperature, humidity, and the composition of rocks and soil. My front
porch light has a light sensor on it that turns it on when it gets dark and off
when it gets light.
A censor is an
individual who decides what may be written, broadcast, and said in public,
based on the prejudices of the ruling class of a given society. A censor is
also a metal ball used to burn incense in, and waved around, generally in a
religious context.
Keep them straight this way: Sensor is related to senses. A
remote mechanical sensor takes the place of human senses, to a very limited
degree. Both words start with an "s". Censor is either related to incense, or censorship...and all three of
those words have the letters “cens” in them.
