This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up their fundamentals on the hall effect.The Hall Effect is the most common method of measuring a magnetic field. The hall effects sensors are very popular and have many contemporary applications for example they can be found in vehicles as wheel speed sensors, camshaft position sensors, switches, MEMS, proximity sensors, compasses, and so on. The element of the Hall effect magnetic sensors provides very small voltage, therefore these devices are usually manufactured with built-in high gain amplifiers. The hall effect sensors are less expensive, operates in different temperature range, and are reliable.There are two types of hall effect sensors, one provides analog and the other is a digital output. The hall effect principle is used in magnetic field sensing equipment, proximity detectors, multiplier applications to provide the actual multiplications, etc The high-speed operation type and low current consumption type are the two types of Hall effect ICs. The hall effect sensors are highly reliable, offer high-speed operation, offer pre-programmable electrical angles & output, and are the ability to work in a wide temperature range.1).
