Distance sensors actually measure the angle, then calculate the distance using triangulation, which provides a relationship between angle and distance: Obviously, you can progressively rotate this assembly to known angles and stop when you measure the expected distance. Then you know you're facing your object.

EO/IR sensor is integrated. Performance of an EO/IR sensor depends upon the optics, detector, and display, in addition to factors mentioned it is unwise to evaluate the potential utility of an EO/IR sensor from specifications alone, that is, without using a detailed engineering model. Nevertheless, all other things being equal, it can be argued that, for an imaging sensor designed ...

It outputs an analog voltage corresponding to the distance that varies from roughly at 15cm to at 150cm. This value would be read by the Arduino using the analogRead () function. Now, while this sensor is quite accurate between the ...

· Now if we consider a different Sharp IR distance sensor we have to calculate that formula ourself. Take the GP2Y0A02YK0F for example: this sensor is capable of detecting obstacles in a range between 20 cm and 150 cm (as we know from the sensor datasheet). So in order to obtain the formula we first need to compile a table where we have: in the first column, the distances - expressed in cm ...
where d n is the distance from the mouse to the n'th sensor. If (x m, y m) are the coordinates of the mouse, you also have d n = (x m − x n) 2 − (y m − y n) 2 for each of the 3 sensors.
The task. In this project, I connected a 2YA21 Sharp Infrared Proximity sensor to an Arduino to test the functionality of the sensor. I was primarily aided by a tutorial on bildr, which was incredibly helpful. It provided both the schematic and code that I used. The materials I began with were an Arduino and the 2YA21 sensor, shown below.
Distance sensors equipped with IR light-emitting diodes (LEDs) often operate on the principle of triangulation: calculation of distance according to the angle of a reflected IR beam off a surface. When the LED focuses a beam of light on a surface, that light is reflected in all directions. A distance sensor adjacent to the LED source acquires a reflected signal and an integrated charge-coupled ...

· An IR distance sensor uses a beam of infrared light to reflect off an object to measure its distance. The distance is calculated using triangulation of the beam of light. The sensor consists of an IR LED and a light detector or PSD (Position Sensing Device). When the beam of light gets reflected by an object, the reflected beam will reach the light detector and an ‘optical spot’ will form on the PSD.
