Sensors
Por: Flora Gibson
Acoustic, Sound or Vibration:
Measure sounds or vibrations, for
example, earthquake tremores.
Usually turned into voltage or (with
sound) amplified.
Geophone: converts
ground movement into
voltage, which are
analysed for earth
structure
The Lace Sensor is a guitar pickup
A microphone is an acoustic-to-electric transducer or
sensor that converts sound into an electrical signal
Proximity and Presense: Activated by
movement, or cuts in the light produced
by machine.
A motion detector is a device that
contains a physical mechanism or
electronic sensor that quantifies motion
that can be either integrated with or
connected to other devices that alert
the user of the presence of a moving
object within the field of view
A wired glove is a glove-like input device for
human-computer interaction
A Passive InfraRed sensor (PIR sensor) is an electronic device
that measures infrared (IR) light radiating from objects in its field
of view
Temperature: Measuring
temperature in the atmosphere,
object, etc.
A thermometer is a device that
measures temperature or
temperature gradient using a variety
of different principles
A heat flux sensor is a commonly used name for a transducer
generating a signal that is proportional to the local heat flux. This
heat flux can have different origins; in principle convective-,
radiative- as well as conductive heat can be measured
A microwave radiometer (MWR) is a
radiometer that measures microwaves.
Pressure: Senses a change in weight on
an object.
The term tactile sensor usually refers to a
transducer, that is sensitive to touch, force, or
pressure
A pressure sensor measures pressure, typically of gases or liquids.
A barometer is a scientific instrument used to
measure atmospheric pressure A barometer is a
scientific instrument used to measure
atmospheric pressure
Force, Density or Level: Measure
force or density of an object.
A hydrometer is an instrument used to measure the relative
density of liquids
A force gauge is a measuring instrument used
across all industries to measure the force
during a push or pull test.
A strain gauge is a device used to measure the relative displacement between particles in the material body of
an object
Optical, Light or Imaging:
Sensors measuring light or
with light.
A flame detector is a detector that uses optical sensors to detect flames.
Infrared imaging is used extensively for military and
civilian purposes. Military applications include target
acquisition, surveillance and night vision. Nonmilitary uses include remote temperature sensing,
short-ranged wireless communication, spectroscopy,
and weather forecasting.
Photosensors or photodetectors are sensors of light or other electromagnetic energy
Navigation: Used to position
objects in a space.
A gyroscope is a device for measuring or maintaining orientation
A compass is a navigational instrument for determining direction relative
to the Earth's magnetic poles.
An altimeter is an instrument used to measure the altitude of an object above a fixed level
