| A **Hall effect sensor** detects strong magnetic fields, their polarities and the relative strength of the field. In the Hall effect sensors, a magnetic force influences current flow through the semiconductor material and creates a measurable voltage on the sides of the semiconductor. Sensors with analogue output can measure the strength of the magnetic field, while digital sensors give //HIGH// or //LOW// output value, depending on the presence of the magnetic field. | A **Hall effect sensor** detects strong magnetic fields, their polarities and the relative strength of the field.
