Name: Instructor: Task: Date: Velocity Sensors Abstract of Sensor A velocity sensor is a crucial tool that is used to determine the rate of change of position of an object. For instance, the device determines change of position when an object moves forward or backwards.
This means that every step taken by this individual must move the person further from their starting point. The person should not change direction and begin to return to their starting points. Velocity sensors rely on vector as a quantity because velocity is dependent on direction. During an evaluation of velocity, it is essential to track the direction of the object. The velocity sensor indicates the velocity of the entity and the direction information in order to describe the velocity of this object. For instance, the velocity sensor may indicate velocity as 55 mi/hr east (Fraden 31). This provides the differences between velocity and speed because speed does not keep track of direction and it is a scalar quantity. Vector is direction aware and a vector quantity. History of the Sensor Sensors have been around since 1883. They have existed in different forms and for different purposes. The first thermostat was made, in 1883. This thermostat can be considered as the first manmade and modern sensor. The 1940s saw the introduction of infrared sensors. However, these sensors gained wide acceptance, in the 1980s (Fraden 41). Thereafter, motion sensors were introduced and they are widely used in different situations. Sensors were introduced because of human need to convert and compute physical quantities. ...
