HC-SR501 PIR Motion Sensor Module

Product Description:

Specifications:

Features:

• High Sensitivity: Detects even small movements.
• Adjustable Sensitivity: Can be fine-tuned for specific applications.
• Low Power Consumption: Ideal for battery-powered projects.
• Easy to Use: Simple digital output for easy integration.
• Wide Range of Applications: Perfect for security systems, lighting control, and automation projects.

Using the HC-SR501 Module with Arduino:

Required Components:

• Arduino board (e.g., Uno, Nano)
• HC-SR501 PIR Motion Sensor Module
• Jumper wires

Wiring:

1. Power: Connect the VCC pin of the module to the 5V pin of the Arduino.
2. Ground: Connect the GND pin of the module to the GND pin of the Arduino.
3. Output: Connect the OUT pin of the module to a digital pin on the Arduino (e.g., 2).

Arduino Code:

C++

const int motionSensorPin = 2;

void setup() {
  pinMode(motionSensorPin, INPUT);
  Serial.begin(9600);
}

void loop() {
  int sensorState = digitalRead(motionSensorPin);

  if (sensorState == HIGH) {
    Serial.println("Motion detected!");
    // Add your desired action here, e.g., turn on a LED
  } else {
    Serial.println("No motion detected.");
    // Add your desired action here, e.g., turn off a LED
  }

  delay(100);
}

Explanation:

1. Digital Read: The digitalRead() function reads the digital value from the motion sensor pin.
2. Motion Detection: When motion is detected, the sensorState will be HIGH.
3. Action Triggering: You can add your desired actions within the if and else blocks, such as turning on/off LEDs, activating motors, or triggering alarms.
