Any film camera with a light meter, and every digital camera, has a sensor that will do that.
sensor is basically a device which detects and converts your signal of interest into a measurable or observable quantity (mostly an electrical signal). Say for example, a pressure sensor detects pressure and converts it into an electrical output which can be further processed for actuation or to be displayed.
A microphone is an acoustic-to-electric transduceror sensor that converts sound into an electrical signal.
It is an electrical devise that "measures" the oil pressure and converts it into an electrical signal that a computer or the gauge cluster reads.
Interferometric Reflectance Imaging Sensors are a type of sensor that converts a biological response into an electrical signal.
Antenna .- converts propagating electromagnetic waves, to and from conducted electrical signals.Magnetic cartridge. - converts relative physical motion ,to and from electrical signals.Tape head. Disk read-and-write head, - converts magnetic fields on a magnetic medium. to and from electrical signals.Hall effect sensor. - converts a magnetic field., level into an electrical signal.Electrochemical transducerElectromechanical transducer (electromechanical output devices are generically called actuators)Electroacoustic transducerElectro-optical transducer(Photoelectric)ElectrostaticThermoelectricRadioacoustic
TRANSDUCER is a device converts one form of energy into other forms sensor it is device any form into electrical form my point of view ,all the sensors are transducers ,but all the transducers are not sensors
Force transducers are also commonly recognized as force sensors. A force sensor is described as a transducer that converts an input mechanical force into an electrical output signal.
The detonation sensor ( knock sensor ) really cannot be checked by the home mechanic it is either good or bad. It consists of a pressure sensing piezoelectric element that converts pressure differences into electrical signals that can be read by the computer.
A microphone is a device that picks up sound waves, converts the waves in to electrical pulses to be sent down cables or by wifi. A speaker receives the electrical pulses and converts the pulses back in to sound waves that a person can hear and understand.
it is a device that consisting of immobilized layer of biological materials like enzymes,antibody,hormone,nucleic acid,organelles or a whole cell and its contacts with a sensor. The sensor converts the biological signals into electrical signals. It is used medicine and industry.For example:blood glucose level can be detected using biosensor
Centers and refocuses light onto the camera's sensor.
