IR (Infrared) Sensor Module – Pack of 4 | Obstacle Detection, Line Following & Motion Sensing | Compatible with Arduino, Raspberry Pi, and Microcontrollers
This pack includes 4 high-quality IR sensor modules with 3-pin output – ideal for robotics, obstacle detection, automation, and DIY electronics. Each module is equipped with an IR transmitter and receiver to detect nearby objects and surfaces based on infrared light reflection.
Key Features:
- IR Transmitter & Receiver: Detects objects, motion, and edges by sending and receiving infrared signals.
- 3-Wire Interface: Easy to use with VCC, GND, and Digital OUT pins – plug-and-play with Arduino and Raspberry Pi.
- Adjustable Sensitivity: On-board potentiometer allows easy tuning of detection range.
- Digital Output: Sends HIGH or LOW signal based on object proximity.
- Indicator LEDs: Built-in power and detection LEDs for real-time feedback.
Specifications:
- Voltage: 3.3V – 5V DC
- Detection Range: ~2cm to 30cm (adjustable)
- Interface: VCC, GND, OUT
- Mounting Holes: Yes
- Output Type: Digital (High/Low)
Applications:
- Obstacle Avoidance Robots
- Line Following Robots
- DIY Home Automation Systems
- Security/Motion Detection Projects
- School & College STEM Kits
Package Includes:
- 4 x IR Sensor Modules (3-Wire Interface)
Usage Note:
For best results, avoid highly reflective or transparent surfaces in front of the sensor. Use standard jumper wires to connect to Arduino UNO, Mega, Nano, NodeMCU, or Raspberry Pi GPIO pins.
Perfect for hobbyists, students, engineers, and makers working on robotics, automation, and real-world electronics projects.
