Description:

5 Way IR Array (Line Sensor Array)

5 Channel Tracking Sensor Tracking Module Infrared Sensor is based on the infrared reflection sensor, it is often used to make tracking smart cars. The infrared emitting diode of the sensor continuously emits infrared rays. When the emitted infrared rays are reflected by the object, they are received by the infrared receiver and output analogue values. The output analogue value is related to the object distance and the colour of the object. The position of the tracking line is judged by calculating the analogue value of the five outputs.

Connection:

1. VCC: VCC is the power input port, which could access 3.3V ~ 5V voltage
2. GND: GND is the negative input of the power supply
3. OUT1 ~ 5:OUT is the signal output port, MCU link I / O port

Features:

1. Applicable to a variety of platforms including for Arduino /AVR/ARM/PIC
2. High-Quality Tracker Sensor
3. The module is a convenient carrier for eight IR emitter and receiver pairs evenly paced.
4. Distance between each IR Sensor: 15mm
5. Uses 5 sensors for best resolution
6. Great useful in building fast line following and grid navigating robots
7. Comes with easy-to-use digital outputs with a direct connection to microcontrollers
8. The array has mounting holes of 3mm diameter for easy mounting
9. Status LED on each sensor for the detection of black line

Specification:

1. Number of Sensors

• Quantity: 5 individual IR sensor pairs (IR LED + photodiode/phototransistor)

• Arrangement: Linear array, typically evenly spaced

• Purpose: Detect contrast (e.g., black line on white surface)

2. Operating Voltage

• Voltage Range: 3.3V to 5V DC

• Typical: 5V for most microcontroller compatibility (Arduino, etc.)

3. Output Type

• Digital Output: Each sensor provides a HIGH or LOW signal (depending on surface reflectivity)

• Logic Level: TTL-compatible (0V = LOW, 5V = HIGH)

4. Detection Range

• Range: ~1 mm to 3 cm (depends on surface color, ambient light, and module tuning)

• Best Performance: ~1–2 cm from surface

5. Adjustable Sensitivity

• Onboard Potentiometers: Typically one for each sensor to fine-tune threshold levels

• Allows Calibration: For different lighting and surface conditions
