In a large part of the technological processes taking place in many factories and other objects of an industrial nature, include the monitoring of the correctness and effectiveness of the results of the process in real time in accordance with its design settings. An example of such a process is robotic production of moving vehicles, where in addition to ensure the required strength of the material requires a complete repetition of the size of the individual elements within tolerance. One of the tools which are used in this process are digital distance sensors.

One of the most commonly used types of distance sensors laser sensors. The principle of operation of such sensors is a directional emission of the laser beam. In automation, control, measurement and protection, laser sensors provide information about the presence of an object in a stable state of attention and its colour, brightness, size and shape. The output of a laser beam system equipped with a temperature compensation, which allows to increase the measurement accuracy. Laser sensors are part of the construction of several industrial applications and systems from hacking. Success can also serve as sensors in Autonomous intelligent robots - then in case of detecting obstacles at a distance that exceeds the pre-set software threshold is, for example, 2.5 cm, the sensor sends the information to the appropriate logic state on the digital input into the Arduino, and the robot performs the transmission in accordance with the program code necessary maneuvers to prevent a collision with the external object previously detected using the laser sensor.
Time-of-flight is one of the methods that is used in the sensor. Method time-of-flight is to measure the time difference between beginning of signal transmission from the sensor until the return beam of this light, after reflection from the object back to the sensor. In this method can be used with various types of signals (also called signals nośnymi) - the most common is the use of light signals and sound effects, but the most preferred is the use of sensors to infrared light, given the large range, high speed and no danger of damage to the eyes of strangers. In addition, the sensors on the IR is characterized by low susceptibility to interference from the outside and work very well in different light conditions of the environment. Distance sensors using the technology of time-of-light are useful elements in many devices. Autofocus in cameras booster during ascent and landing unmanned aircraft, warning system for preventing collision of vehicles or robots, automation budynkowa - gesture recognition for touch-free adjustment of the intensity of the lighting, automation equipment, sanitary equipment, automatic calculation of product, IoT devices and more are just some applications of sensors time-of-light.
