Arduino Uno Microwave Motion Sensor (RCWL-0516)

This project demonstrates how to interface an Arduino Uno with a microwave motion sensor module (RCWL-0516).

The sensor detects motion within its detection range using microwave signals and outputs a signal that the Arduino reads to determine motion presence.

Components Needed

• Arduino Uno
• RCWL-0516 Microwave Motion Sensor Module
• Jumper Wires
• Breadboard

Block Diagram

Hardware Wiring Explanation:

Connect the output pin of the RCWL-0516 module to digital pin 2 on the Arduino Uno.

Ensure the VCC pin of the module is connected to 5V on the Arduino Uno.

Connect the GND pin of the module to GND on the Arduino Uno.

Wire up the RCWL-0516 module to the Arduino Uno according to the circuit setup section.

Software (Arduino IDE):

Open the Arduino IDE on your computer.

Write or paste the provided program into the IDE.

Select the correct board and port in the Arduino IDE under the Tools menu.

Upload the program to the Arduino.

Open the serial monitor with a baud rate of 9600.

Observe the messages on the Serial Monitor indicating whether motion is detected or not as you move within the sensor's range.

Applications

Notes

Ensure the RCWL-0516 module is placed correctly and oriented as per the manufacturer's guidelines for optimal detection.

Adjust the sensitivity and other parameters of the module if necessary, as some modules may have adjustable settings.

Test the module in the intended application environment to verify detection range and reliability.
