The IEEE Sensors Journal is a biweekly peer-reviewed scientific journal, covering research on sensors. It is published by the IEEE Sensors Council. The editor-in-chief is Zeynep Celik. According to the Journal Citation Reports, the journal has a 2022 impact factor of 4.325, [1] as well as an Eigenfactor at 0.03365, and an Article Influence ...
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.
CCD sensors are used for high end broadcast quality video cameras, and CMOS sensors dominate in still photography and consumer goods where overall cost is a major concern. Both types of sensor accomplish the same task of capturing light and converting it into electrical signals. Each cell of a CCD image sensor is an analog device.
Hall sensors ICs often integrate digital electronics. [26] This enables advanced corrections to the sensor characteristics (e.g. temperature-coefficient corrections), digital communication to microprocessor systems, and may provide interfaces for input diagnostics, fault protection for transient conditions, and short/open-circuit detection.
Because the image sensors in many digital cameras are smaller than the 24 mm × 36 mm image area of full-frame 35 mm cameras, a lens of a given focal length gives a narrower field of view in such cameras. Sensor size is often expressed as optical format in inches. Other measures are also used; see table of sensor formats and sizes below.
