Infrared Proximity Sensor – Sharp GP2Y0A21

Description

Description:
The Sharp distance sensor is a popular choice for application and development that require accurate distance measurements. This IR sensor provides much better performance than other IR alternatives. Interfacing to most microcontrollers is straightforward: the single analog output can be connected to an analog-to-digital (ADC) converter for reading distance measurements. The output can also be connected to a comparator for threshold detection.

Specification:
Similar specification to GP2D12
4.5V to 5.5V operating voltage.
Working distance from 10cm to 80cm.
Analog Output
Output voltage change over distance (2.45V – 0.45V)
