Vehicle instrument is an instrument that measures some parameters in the vehicle, often found on its control panel or dashboard A control panel is a flat, often vertical, area where control or monitoring instruments are displayed or it is an enclosed unit that is the part of a system that users can access, such as the control panel of a security system (also called control unit ). They are found in factories to monitor and control machines or production lines and in places such as nuclear power plants , ships , aircraft and mainframe computers . Older control panels are most often equipped with push buttons and analog instruments, whereas nowadays in many cases touchscreens are used for monitoring and control purposes. A dashboard is a control panel set within the central console of a vehicle or small aircraft. Usually located directly ahead of the driver, it displays instrumentation and controls for the vehicle's operation. An electronic equivalent may be called an electronic instrument cluster, digital instrument panel

Speedometer A speedometer or speed meter is a gauge that measures and displays the nstantaneous speed of a vehicle . Mechanical/Electric Electronic Virtual Speedometer A virtual speedometer is a computer-generated tool that displays the current speed of a vehicle or object. The virtual speedometer typically calculates the object's speed based on the distance it travels over time.
Electronic Speedometer Many modern speedometers are electronic . In designs derived from earlier eddy-current models, a rotation sensor mounted in the transmission delivers a series of electronic pulses whose frequency corresponds to the (average) rotational speed of the driveshaft , and therefore the vehicle's speed, assuming the wheels have full traction . The sensor is typically a set of one or more magnets mounted on the output shaft or (in transaxles) differential crown wheel, or a toothed metal disk positioned between a magnet and a magnetic field sensor . As the part in question turns, the magnets or teeth pass beneath the sensor, each time producing a pulse in the sensor as they affect the strength of the magnetic field it is measuring
Odometer An odometer or odograph is an instrument used for measuring the distance traveled by a vehicle, such as a bicycle or car. The device may be electronic, mechanical, or a combination of the two ( electromechanical ).

A Hall effect sensor (or simply Hall sensor) is a type of sensor which detects the presence and magnitude of a magnetic field using the Hall effect. The output voltage of a Hall sensor is directly proportional to the strength of the field. It is named for the American physicist Edwin Hall.
