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.

A GPS receiver is a device that can receive information from a global navigation satellite system and calculate its position on the Earth. A GPS receiver uses a constellation of satellites and ground stations to compute position and time almost anywhere on Earth.
