Sharp GP2Y0A21YK Infrared Proximity Sensor 10-80 cm
This SHARP distance sensor
bounces IR off objects to determine how far away they are. It returns
an analog voltage that can be used to determine how close the nearest
object is. Comes with 12″ long 3-JST interface wire. These sensors are
good for short-range detection. For over 1 m distance, we suggest using
To use, connect the black wire to ground, red wire to 5V and white
wire to the analog input. The analog voltage out will range from 3V when
an object is only 4″ (10 cm) away and 0.4V when the object is 32″ (80
This sensor draws current in large,
short bursts, and the manufacturer recommends putting a 10 µF capacitor
or larger across power and ground close to the sensor to stabilize the
power supply line
