COO

Description:

The SHARP Distance Sensor uses infrared (IR) light to detect objects and measure their distance. It emits IR light, which reflects off objects and returns an analog voltage that can be used to calculate the proximity of the nearest object. This sensor is ideal for short-range detection, typically up to 1 meter. For distances beyond 1 meter, we recommend using sonar sensors for better accuracy.

The sensor comes with a 12-inch 3-pin JST interface wire for easy connection.
To use:

  • Connect the black wire to ground,
  • Connect the red wire to 5V,
  • Connect the white wire to an analog input on your microcontroller.

The output voltage varies based on the object’s distance:

  • 3V when an object is 4 inches (10 cm) away.
  • 0.4V when the object is 32 inches (80 cm) away.

Specification:

Model GP2Y0A21YK0F (10 to 80 cm)
Operating Voltage (VDC): 4.5 ~ 5.5
Distance measuring range (cm) 10 ~ 80 cm
Screw Holes 37mm apart, 3 mm diameter.
Connecting cable length (cm) 15
Length (mm): 44
Width (mm): 18
Height (mm): 13
UPC 602716546003

Application:

  • Motor Drive & Control

  • Sensing & Instrumentation

  • Industrial

Note:

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.


Package Includes:

1 x Sharp Distance Measuring Sensor unit 10 to 80 cm.

1 x Connecting cable.
