 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. GPS receivers (figure {{ref>gps1}}) are used for navigation only in the outdoor area because they need to receive signals from the satellites, which is complicated inside the buildings. The GPS location's precision can vary depending on the number of visible satellites, weather conditions, and current satellites' placement. The GPS receiver is often connected to a microcontroller with a serial communication port and sends information according to the NMEA scheme (figure {{ref>gps2}}). A GPS receiver is a device that can receive information from a global navigation satellite system and calculate its position on the Earth.
