Description
Without sensors most electronic applications would not exist—sensors perform a vital function, namely providing an interface to the real
world. Hall effect sensors, based on a magnetic phenomena, are one of the most commonly used sensing technologies today. In the 1970s
it became possible to build Hall effect sensors on integrated circuits with onboard signal processing circuitry, vastly reducing the
cost and enabling widespread practical use. One of the first major applications was in computer keyboards, replacing mechanical contacts.
Hundreds of millions of these devices are now manufactured each year for use in a great variety of applications, including automobiles,
computers, industrial control systems, cell phones, and many others.
The importance of these sensors, however, contrasts with the
limited information available. Many recent advances in miniaturization, smart sensor configurations, and networkable sensor technology
have led to design changes and a need for reliable information. Most of the technical information on Hall effect sensors is supplied
by sensor manufacturers and is slanted toward a particular product line. System design and control engineers need an independent, readable
source of practical design information and technical details that is not product- or manufacturer-specific and that shows how Hall effect
sensors work, how to interface to them, and how to apply them in a variety of uses. This book covers:
• the physics behind Hall effect
sensors
• Hall effect transducers
• transducer interfacing
• integrated Hall effect sensors and how to interface to them
• sensing
techniques using Hall effect sensors
• application-specific sensor ICs
• relevant development and design tools
This second edition
is expanded and updated to reflect the latest advances in Hall effect devices and applications!
Information about various sensor
technologies is scarce, scattered and hard to locate. Most of it is either too theoretical for working engineers, or is manufacturer
literature that can’t be entirely trusted. Engineers and engineering managers need a comprehensive, up-to-date, and accurate reference
to use when scoping out their designs incorporating Hall effect sensors.
Audience:
PRIMARY MARKET: Electronics design engineers, mechanical engineers, and engineering managers working in a vast array of application areas—
automotive, computers, medical, embedded, military, aerospace/aviation, , construction, etc.; instrumentation engineers;
test engineers
SECONDARY MARKET: electronics technicians; inhouse training departments of electronics
manufacturers and other technology companies
