Sharp GP2Y0A02 F 23 Distance Sensor 20-150cm Analog Output
Sharp GP2Y0A02 F 23 – 20-150 cm Infrared Distance Sensor
The Sharp GP2Y0A02 F 23 is an infrared proximity sensor that uses triangulation to measure distances from 20 cm to 150 cm with high reliability. It outputs an analog voltage that corresponds to the detected distance, allowing direct connection to microcontrollers with ADC for digital distance computations. This sensor is widely used in robotics for obstacle avoidance, in automation for object detection, and in industrial systems for non-contact measurement.

Compatibility
This sensor works with any 5V microcontroller that has an analog input, such as Arduino Uno, Nano, or Mega. It can also interface with 3.3V boards like ESP32 or Raspberry Pi Pico by using a voltage divider for the output signal. The analog output makes it easy to integrate with existing code libraries for distance calculation.
Wiring Notes
Connect VCC to 5V, GND to ground, and the output pin directly to an analog input. Keep wires short and avoid routing near noisy components like motors. A 10 µF capacitor across VCC and GND near the sensor reduces measurement jitter.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, connect the sensor's output to any analog pin on Arduino and use the analogRead() function to obtain a value proportional to distance.
How accurate are the distance readings?
Accuracy is typically within a few centimeters, depending on ambient light and object reflectivity. White, matte surfaces yield the best results.
Can it be used outdoors in sunlight?
The sensor may give unreliable readings in direct sunlight because of infrared interference. It is best used indoors or in shaded environments.
