รายละเอียดสินค้า: IR Distance Sensor Kit - Sharp GP2Y0A41SK0F

DESCRIPTION

This short range of the GP2Y0A41SK0F makes it great for detecting very close objects. It has a faster sensing time and uses less current than the Sharp GP2D120 (which has been discontinued by Sharp). This sensors single analog output can be connected to an analog-to-digital converter for taking distance measurements. Or, the output can be connected to a comparator for threshold detection. Detection range is approximately 4 cm to 30 cm (1.5″ to 12″). This kit includes wires and compatible connector to connect to the sensor.

Sharp infrared distance sensore are extremely light weight, low power and compact, making them ideal for integration into mobile automation applications like UAVs, UGVs, and remotely controlled semi-autonomous cars. These sensors are perfect for collision avoidance and object detection, and can even be used for indoor mapping applications. Their narrow beamwidth of approximately 6cm at half of the maximum range allows for precise mapping of detected objects relative to the sensor. Since Sharp sensors use infrared light, their output can be variable in bright sunlight or when detecting glossy objects like glass or metal. Be sure to test the sensor in applicable lighting conditions and object reflectivities. Our application note provide more detail on detecting different object types in various lighting conditions. 

These types of infrared distances sensors use triangulation to determine the distance from the sensor to objects placed in their beam pattern. A pulsed infrared light source creats the illumination beam, and a small linear CCD array receives light reflected off any object in the beam path. If there is no object in the beam path, the light is never reflected, and the reading shows no object. If the light reflects off an object, it returns to the detector and creates a triangle between the point of reflection, the emitter and the detector. By using triangulation, the sensor can compute the distance to the object which reflected the light. Our Sharp Infrared Comparison Article provides more details on how this sensor works. Also, in order to quickly convert this sensors analog output to a linearized distance using only interger math (e.g. when running on a low power microcontroller), see our example code in our Linearizing Sharp Range Data.
