GP2Y0E03 | Distance Sensor For Arduino
The GP2Y0E03 Sharp Microelectronics Distance Sensors are a popular choice for many projects that require accurate distance measurements.
By detecting the reflective light spot position on the detector, This sensors measure the distance to an object. A CMOS image sensor can be used to measure distance with high accuracy. This sensor is good for distance range between 4cm-50cm. The long range makes them a good alternative to ultrasonic sensors.

Introduction
The variety of the reflectivity of the object, the environmental temperature and the operating duration are not influenced easily to the distance detection because of adopting the triangulation method.
Due to the adoption of the triangulation method, the variation of reflectivity of the object, the environmental temperature and the operating duration are not easily influenced to distance detection.
Interfacing of this distance sensor to microcontrollers such as Arduino, PIC, AVR, STM32 is straightforward as this module gives output voltage corresponding to the detection distance and digital(I2C) data. So this sensor can also be used as a proximity sensor.
