Arduino Uno IR Infrared Sensor

This project demonstrates how to use an IR infrared sensor module with an Arduino Uno to detect the presence of objects.

The IR sensor emits infrared radiation and detects reflected radiation from objects in its field of view.

The Arduino reads the sensor's analog output and determines if an object is detected based on a threshold value, which is displayed on the serial monitor.

Components Needed

• Arduino Uno
• IR Infrared Sensor Module
• Jumper Wires
• Breadboard

Block Diagram

Hardware Wiring Explanation:

Connect the IR infrared sensor module to the Arduino Uno as described in the circuit setup section.

Software (Arduino IDE):

Open the Arduino IDE and create a new sketch.

Copy and paste the provided Arduino code into the sketch.

Upload the code to the Arduino Uno.

Monitor the Output:

Open the serial monitor with a baud rate of 9600.

Place objects within the sensor's range. Observe the serial monitor to see the sensor values and object detection status.

Applications

Notes

Ensure the IR infrared sensor module is correctly connected to the Arduino Uno and powered.

Test the sensor in different lighting conditions and adjust the threshold if necessary for reliable object detection.
