... AND SENSORS
Electronics can perceive changes in the
environment as well — particularly through
sensors, also known as detectors. There are
detectors for gas, temperature, humidity,
sound, light, and a lot of other things.
Electronic sensors can also detect things that
we cannot perceive at all through our own
senses, such as electrical and magnetic fields.
Sensors & Detectors
We humans perceive the
world through our
senses — through our
eyes, ears, nose, mouth,
and skin. Our senses are
very delicate. The
human sense of smell,
for example, is capable
of perceiving even the
slightest distinctions.
