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 wired glove is a glove-like input device for human-computer interaction

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 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.

A pressure sensor measures pressure, typically of gases or liquids.

The term tactile sensor usually refers to a transducer, that is sensitive to touch, force, or pressure

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 force gauge is a measuring instrument used across all industries to measure the force during a push or pull test.

A hydrometer is an instrument used to measure the

relative density of liquids

A strain gauge is a device used to measure the relative displacement between particles in the material body of an object

Photosensors or photodetectors are sensors of light or other electromagnetic energy

Optical, Light or Imaging: Sensors measuring light or with light.

Infrared imaging is used extensively for military and civilian purposes. Military applications include target acquisition, surveillance and night vision. Non-military uses include remote temperature sensing, short-ranged wireless communication, spectroscopy, and weather forecasting.

A flame detector is a detector that uses optical sensors to detect flames.

Navigation: Used to position objects in a space.

An altimeter is an instrument used to measure the altitude of an object above a fixed level

A compass is a navigational instrument for determining direction relative

to the Earth's magnetic poles.

A gyroscope is a device for measuring or maintaining orientation
