Key Features of 5mm IR Transmitter Receiver Pair 10(pcs)
- Matched pairs: Each pack includes pre-matched IR transmitter LEDs and receiver photodiodes tuned to 940nm for reliable detection
- Bulk value pack: 10 pairs give you enough components for multiple projects, prototypes, or classroom use
- Breadboard friendly: Standard 5mm through-hole package plugs directly into breadboards and perfboards
- Versatile sensing: Works for proximity detection, object counting, line following, encoder wheels, and IR communication
- Easy identification: Transmitter (clear/slightly blue tint) and receiver (dark/black tint) are visually distinguishable
- Low power consumption: Operates at just 20mA, perfect for battery-powered and microcontroller-driven circuits
- 100% authentic from trusted suppliers
Perfect For
- Line-Following Robot: Mount pairs underneath a robot chassis to detect black lines on white surfaces for autonomous navigation
- Obstacle Detection Sensor: Build a proximity sensor module that detects objects within 5-30cm range for collision avoidance
- Object Counter: Create an IR break-beam counter for production lines, visitor counting, or inventory tracking systems
- IR Remote Control System: Design a custom infrared remote control and receiver for home automation or appliance control
- Rotary Encoder / Tachometer: Pair with a slotted disc to measure motor RPM, wheel speed, or shaft rotation
- Security Beam Alarm: Set up an invisible IR tripwire that triggers an alarm or notification when the beam is broken
- Optical Data Communication: Transmit simple data wirelessly over short distances using modulated IR light
- Hand Gesture Sensor: Detect hand proximity and simple gestures for touchless control interfaces
How to Use
- IR Transmitter (LED): Connect through a 100Ohm-220Ohm current-limiting resistor to 3.3V or 5V supply; the LED emits invisible 940nm infrared light
- IR Receiver (Photodiode): Connect in reverse bias with a pull-up resistor (10kOhm typical); output voltage changes when IR light is detected
- With Arduino/ESP32: Read the receiver output on an analog or digital pin; use analogRead() for distance estimation or digitalRead() for simple detection
- Tip: Use a small tube or shrink wrap around the receiver to reduce ambient light interference and improve directionality

Frequently Asked Questions
How do I tell the transmitter apart from the receiver?
The IR transmitter LED has a clear or slightly bluish-tinted lens, while the receiver photodiode has a dark or black-tinted lens. The transmitter also typically has a slightly longer anode lead. If unsure, the transmitter will show a faint glow when viewed through a phone camera.
What is the effective detection range?
The typical detection range is 5-30cm depending on your circuit design, current through
