Infrared sensor rig in detecting various object shapes

Abstract

This paper describes the application of infrared sensor installed in a sensor rigto measure the distance of the object located at the centre of the plate. Data received by the sensor rig that is fully controlled by Arduino as a microcontroller, is then saved in a text file using CoolTerm terminal application. Post processing of the data is fully run using the Matlab software to reconstruct the image from the data obtained by infrared sensor. Most of the objects used throughout this research are polygon shapes such as cylinder, rectangle, hemisphere, oval, trefoil, and curvilinear. The sensitivity of the infrared sensor used during the experiment should be considered in order to obtain accurate result and reduce the noise during the data captured process. The closest distance of infrared sensor from the measured object is set into 5 cm. Results show that this sensor is capable to detect any changes in distance measurement and image from the object can be reconstructed.
