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.

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.
Where to Buy?
This Infrared distance sensor made by Sharp Microelectronics. It is available in many online stores. Its price varies, but you can get it for approximately $3.8 in most stores.
Simple Arduino project to alert me when dust collection bin has a full.
It’s an excellent choice if you want a High precision measurement distance sensor without spending too much budget. Its also used as proximity detection. Best alternative for ultrasonic distance sensor. Performance under sunlight is not tested yet(please update in comment, if anyone Test how well the array works under sunlight).
