sensor
device that measures a physical quantity and converts it into a signal
resistance thermometer
type of temperature sensor (thermometer)
motion detection
process of detecting a change in the position of an object relative to its surroundings or a change in the surroundings relative to an object
sun sensor
spacecraft instrument that senses the direction to the Sun
gravitational-wave detector
device used to measure gravitational waves
wavefront sensor
device used to measure aberrations of an optical wavefront
position sensor
sensor that facilitates measurement of mechanical position
star tracker
device that senses the direction to one or multiple stars
orientation sensing
orientation sensor can be found in some digital cameras. By recording the orientation at the time of capture, the camera's software can determine whether the image should be oriented to landscape or portrait format
rotary encoder
device that converts the angular position (motion) to an analog or digital code
electronic nose
sensor
gas detector
device that detects the presence of gases in an area
capacitive sensing
technology
tunable resistive pulse sensing
single-particle technique used to measure the size, concentration and zeta potential of particles as they pass through a size-tunable nanopore
charge-coupled device
device for the movement of electrical charge
radar detector detector
sensor used by the police to detect radar detectors
endoscopic wireless capsule
peroral sensor capsule transmitting biomedical data via a wireless channel
occupancy sensor
