2-15 CM Analog Output Distance Measurement Sensor Sharp GP2Y0A51SK0F

Description

What it is

The Sharp GP2Y0A51SK0F distance sensor is a device that measures the distance from an object within a range of 2 to 15 cm. It emits a laser beam and measures the time taken for the beam to return to the sensor, from which it calculates the distance. The sensor’s output is analog, so it can be directly connected to an Arduino or microcontroller for processing.

Features

• Distance measurement range: 2-15 cm
• Output type: analog
• Brand: Sharp
• Model: GP2Y0A51SK0F
• SKU: ARD0011128
• Price: 9.49 €

What it is for

The Sharp GP2Y0A51SK0F sensor is ideal for a wide range of applications, including:

• Window and door alarm systems
• Robots and autonomous vehicles
• Proximity sensors for electronic devices
• Monitoring of objects and people

Its analog output makes it compatible with Arduino and other microcontrollers.

Tutorial: How to use 2-15 CM Sharp GP2Y0A51SK0F Sensor

What you need

• Arduino or compatible
• 5V power supply cable
• 10kΩ resistor
• Workbench

Steps

1. 1. Connect the sensor to pin A0 of Arduino.
2. 2. Connect the resistor between the VCC and GND pins of the sensor.
3. 3. Connect the GND pin of the sensor to GND of Arduino.
4. 4. Upload the following code to Arduino.
5. 5. Check the measured distance on the serial monitor.
6. 6. Verify the accuracy of the sensor in the datasheet.
7. 7. Adapt the code to your project.
8. 8. Test the sensor in various environmental conditions.

Example code

```
void setup() {
  Serial.begin(9600);
}

void loop() {
  int distance = analogRead(A0);
  Serial.println(distance);
  delay(500);
}
```

Mini project

Create an entry door alarm system. Connect the sensor to a relay and raise the voltage on a buzzer.

Common mistakes

• Do not verify correct connection before uploading the code.
• Do not use the correct resistor.
• Connect the sensor directly to VCC without resistor.
• Do not test the sensor in different environmental conditions.

Recommended accessories

• Relay
• Buzzer
• 5V power supply cable
