Sharp GP2Y0A21YK0F 10~80cm Infrared Proximity Distance

Description

The Sharp GP2Y0A21YK0F is an infrared proximity sensor that is used to measure distances from 10 to 80 centimeters. This sensor works by emitting an infrared signal and measuring the amount of time it takes for the signal to bounce back after hitting an object.

The sensor has a compact design with dimensions of 29.5mm x 13mm x 21.6mm, making it easy to integrate into a variety of projects. It has a built-in amplifier circuit that provides a voltage output proportional to the distance detected. The output voltage ranges from 3.1V to 0.4V, which corresponds to distances of 10cm to 80cm.

The Sharp GP2Y0A21YK0F operates at a supply voltage of 4.5V to 5.5V and consumes very little power, making it suitable for battery-powered applications. It has a response time of 38ms, which allows for fast and accurate distance measurements.

This sensor is commonly used in robotics, automation, and other applications that require proximity detection or distance measurement. It is easy to use and can be connected to microcontrollers and other electronic devices with a simple analog voltage input. Overall, the Sharp GP2Y0A21YK0F is a reliable and versatile infrared proximity sensor that provides accurate distance measurements in a compact package.
