Article from Texas Instruments on various common misconceptions about Hall-effect sensors as well as real-world applications. Link here (PDF) Hall-effect sensors are commonly used in automotive and industrial systems for applications including proximity detection, linear displacement measurement and rotary encoding. Currently, the high system performance requirements of modern applications have led to IC manufacturers increasing […]

App note: What are Hall Effect (ac, dc) clamp meters?
Fluke article on Hall Effect used on clamp meters. Link here Hall Effect clamp meters can measure both ac and dc current up to the kilohertz (1000 Hz) range. Like current transformer types, Hall Effect clamp meters use rigid iron jaws to concentrate the magnetic field that encircles the conductor being measured. Unlike current transformer […]
App note: Using the Si72xx hall-effect magnetic position sensors
App note from Silicon Labs on their hall-effect Si72xx magnetic sensor to sense position, count revolution and security system seal tamper sensing. Link here (PDF) These devices all measure magnetic field in the axis perpendicular to the package. All of these parts share the attributes of low power, high sensitivity, and low noise. The simplest […]
App note: Hall effect liquid level sensing
A hall effect sensor as liquid level sensor app note from TT Electronics.
App note: Hall effect sensing and application
Hall effect sensing introduction app note from Honeywell. The Hall effect has been known for over one hundred years, but has only been put to noticeable use in the last three decades. The first practical application (outside of laboratory experiments) was in the 1950s as a microwave power sensor. With the mass production of semiconductors, […]
Using a ACS712 hall-effect current sensor
Raj made a two part tutorial on how to interface a PIC microcontroller with the ACS712 hall-effect current sensor. The first part covers hall-effect theory and basic operation of the ACS712. The second part covers the actual PIC interface, which is simply reading the output voltage of the sensor. Sensing and controlling current flow is […]
