Sharp GP2Y0A02 F 23 Digital Distance Measuring Sensor
Sharp GP2Y0A02 F 23 Digital Distance Measuring Sensor
The Sharp GP2Y0A02 F 23 is a digital distance measuring sensor, a type of infrared (IR) proximity sensor designed for accurate measurement of distances up to 23 cm (9 inches). This compact sensor is widely used in various applications, including robotics, automation, and IoT projects, where precise distance measurement is essential.
The GP2Y0A02 F 23 sensor uses infrared light to measure the distance to an object. It emits a modulated IR beam, which is then reflected back to the sensor by the object. The sensor calculates the distance based on the time-of-flight principle, where the time delay between the emitted and reflected IR signals is proportional to the distance. The sensor outputs a digital signal indicating the measured distance, making it easy to interface with microcontrollers and other digital systems.

NC: Not connectedCode Examples### Example 1: Basic Distance Measurement using Arduino```c++
const int sensorPin = 2; // Connect VIN to digital pin 2
const int modePin = 3; // Connect EN to digital pin 3void setup() {
pinMode(sensorPin, INPUT);
pinMode(modePin, OUTPUT);
digitalWrite(modePin, HIGH); // Set mode to measurement mode
}void loop() {
int distance = digitalRead(sensorPin);
distance = distance 0.0254; // Convert to inches
Serial.print("Distance: ");
Serial.print(distance);
Serial.println(" inches");
delay(50); // Take measurements every 50ms
}
```### Example 2: Obstacle Detection using Raspberry Pi (Python)```python
import RPi.GPIO as GPIO
import timeGPIO.setmode(GPIO.BCM)
sensor_pin = 17 # Connect VIN to GPIO 17
mode_pin = 23 # Connect EN to GPIO 23GPIO.setup(sensor_pin, GPIO.IN)
GPIO.setup(mode_pin, GPIO.OUT)
GPIO.output(mode_pin, GPIO.HIGH) # Set mode to measurement modewhile True:
distance = GPIO.input(sensor_pin)
if distance < 1000: # Adjust threshold value as needed
print("Obstacle detected!")
else:
print("No obstacle detected")
time.sleep(0.1) # Take measurements every 100ms
```### Example 3: Gesture Recognition using ESP32 (C++)```c++
#include <WiFi.h>const int sensorPin = 32; // Connect VIN to digital pin 32
const int modePin = 33; // Connect EN to digital pin 33void setup() {
pinMode(sensorPin, INPUT);
pinMode(modePin, OUTPUT);
digitalWrite(modePin, HIGH); // Set mode to measurement mode
Serial.begin(115200);
}void loop() {
int distance = digitalRead(sensorPin);
if (distance < 500) { // Adjust threshold value as needed
Serial.println("Hand detected!");
// Perform gesture recognition logic here
} else {
Serial.println("No hand detected");
}
delay(50); // Take measurements every 50ms
}
```Note: In all examples, ensure to connect the sensor's VIN pin to a digital input pin on your microcontroller, and the EN pin to a digital output pin. Adjust the threshold values and measurement intervals according to your specific application requirements.
