Responsivity is a function of the wavelength of the incident radiation and of the sensor's properties, such as the bandgap of the material of which the photodetector is made. [1] One simple expression for the responsivity R of a photodetector in which an optical signal is converted into an electric current (known as a photocurrent) is
Some sensors require external voltage or current source of excitation, These sensors are called active sensors. (E.g. a temperature sensor like a thermistor & RTD, a pressure sensor (piezo-resistive and capacitive), etc.). The stability and precision of the excitation signal directly relates to the sensor accuracy and stability.
Sensitivity second definition: the minimum magnitude of input signal required to produce an output signal with a specified signal-to-noise ratio of an instrument or sensor. Examples of the use of this definition are given in the sections below on receivers and electronic sensors.

The 2023 NFL season has arrived, kicking off five straight months of football bliss. From previews of all 32 teams to Fantasy player rankings to staff Super Bowl predictions, here's everything you ...
A digital sensor is an electronic or electrochemical sensor, where data is digitally converted and transmitted. Sensors are often used for analytical measurements, e.g. the measurement of chemical and physical properties of liquids. Examples of measured parameters are pH value, conductivity, oxygen, redox potentials.
SDI-12 (Serial Digital Interface at 1200 baud) is an asynchronous serial communications protocol for intelligent sensors that monitor environment data. These instruments are typically low-power (12 volts), are used at remote locations, and usually communicate with a data logger or other data acquisition device.
For decades, the NFL has relied on stripe-shirted humans with imperfect judgement and obstructed views to spot footballs; to determine whether runners reach yard lines or goal lines; to pinpoint ...
