A motion detector is a device that detects moving objects, particularly people.
Transducer
A transducer is a device that converts one form of energy to another.
Microphone
A microphone, colloquially nicknamed mic or mike (/ˈmaɪk/), is a transducer that converts sound into an electrical signal.
Potentiometer
A potentiometer, informally a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
Thermistor
A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors.
Josephson effect
The Josephson effect is the phenomenon of supercurrent—i.
Biosensor
A biosensor is an analytical device, used for the detection of an analyte, that combines a biological component with a physicochemical detector.
Photoresistor
A photoresistor (or light-dependent resistor, LDR, or photocell) is a light-controlled variable resistor.
Thermocouple
A thermocouple is an electrical device consisting of two different conductors forming electrical junctions at differing temperatures.
Scintillator
A scintillator is a material that exhibits scintillation — the property of luminescence, when excited by ionizing radiation.
Level sensor
Level sensors detect the level of liquids and other fluids and fluidized solids, including slurries, granular materials, and powders that exhibit an upper free surface.
Gunfire locator
A gunfire locator or gunshot detection system is a system that detects and conveys the location of gunfire or other weapon fire using acoustic, optical, potentially other types of sensors, as well as a combination of such sensors.
Carbon dioxide sensor
A carbon dioxide sensor or CO2 sensor is an instrument for the measurement of carbon dioxide gas.
Fluorescent glucose biosensor
Fluorescent glucose biosensors are devices that measure the concentration of glucose in diabetic patients by means of sensitive protein that relays the concentration by means of fluorescence, an alternative to amperometric sension of glucose.
Current sensing techniques
Current sensing is a vital task in electrical sector, where the current information is required for monitoring and control purposes.
Phototube
A phototube or photoelectric cell is a type of gas-filled or vacuum tube that is sensitive to light.
Array processing
Array Processing: Signal Processing is a wide area of research that extends from the simplest form of 1-D signal processing to the complex form of M-D and array signal processing.
Unattended ground sensor
The unattended ground sensor (UGS) is under development as part of the United States Army's Future Combat Systems Program.
PEDOT-TMA
Poly(3,4-ethylenedioxythiophene)-tetramethacrylate or PEDOT-TMA is a p-type conducting polymer based on 3,4-ethylenedioxylthiophene or the EDOT monomer.
Cameleon (protein)
Cameleon is an engineered protein based on variant of green fluorescent protein used to visualize calcium levels in living cells.
NODE (wireless sensor)
NODE+ (wireless sensor platform) is a first-generation handheld sensor measuring 1 inch in diameter and 3.
