GP2Y0A51SK0F Infrared Sensor Features
Sharp GP2Y0A51SK0F is an IR sensor that uses infrared wave to measure distance. The output of the sensor is analog voltage, which can be easily read by the microcontroller’s ADC converter. This sensor can be used in industry and especially in robotics. The efficient range of this module is 2 to 15 cm.
Note
At distances over 15cm, the sensor’s output is not accurate (usually shows higher than real value).
You can download the datasheet of this module here.
GP2Y0A51SK0F Infrared Sensor Pinout
This module has 3 pins:
- VCC: Module power supply – 5V
- GND: Ground
- OUT: The output of the module which is analog voltage.

Thank you for your tutorial.
I would like to make it in raspberry, do you have the code ?
You’re quite welcome!
Unfortunately, we don’t have a tutorial for that. You can check the link below.
