The 80cm Infrared Proximity Sensor is a General Purpose Type Distance Measuring Sensor based on Sharp GP2Y0A21YK, which is a wide-angle distance measuring sensor. This proximity sensor takes a continuous distance reading and returns a corresponding analog voltage with a range of 10cm to 80cm.
Features
Non-contact distance detection area between 10cm to 80cm
The Sharp GP2Y0A21YK0F is a distance sensor using infrared for measuring the distance to the object. This device outputs the voltage corresponding to the detection distance. So this sensor can also be used as a proximity sensor.
