What is the triangulation sensor?
Triangulatory sensor is a device that usually uses optics to determine the position of the object. For this type of system, at least one light emitting (LED) and one photodiode is usually necessary, although other sensors can also be used. The location of the object can be triangulated on the basis of the angles of the LED light and the light that returns to the photodiode. One common use of this type of triangulation sensor is like a safety mechanism in the automatic door. These systems are able to determine when the person is close to the door, because the person will tend to interfere with the path of light from the triangulation sensor and cause to reflect at a different angle or not at all.
triangulation is a process that can be used to find the location of the object using two or more known locations. In both cases, it uses some familiar data and trigonomic identity to determine unknown information. One examples of triangulation is the way the cell -referee signal can be placed according to its vicinity of two or more cellulartower. Another is how the position of the building can be determined on the basis of a triangle drawn between this object and the known baseline, resulting in two known angles and one known distance measurement. Trigonomic identities can then be used to determine an unknown distance.
optical triangulation sensors can be useful in robotics and when measuring objects that are fragile and can easily be damaged if the probe is physically touched. These sensors usually use LED or other light source and one or more receptors such as photodios. The distance between the receptors and the light source is known, so it is also possible to determine the angle at which the light left the ice and arrived at the photodiode. These three well -known characters can then be used to determine the distance of the USEING trigonomic identity.
Another common use of the triangulation sensor is in the safety mechanisms of automatic doors. This oneP sensor triangulation physically measures the location of the floor, but can perceive when this position changes. When these devices are calibrated, the photodiode receptor is placed so that the LED light hit the floor, reflects and then hits it. The system is able to feel when a person is close to the door because he tends to prevent light and causes not to ate a photo. This informs the system that a person or other object is present, which can help prevent a collision between the automatic doors and a pedestrian.
