Overview:
The ELECFREAKS PlanetX 4-Channel Tracking Sensor is designed for precise and intelligent line-following in robotics applications. With four built-in photocell receivers and fill-light LEDs, it can dynamically adjust to various surface colors and lighting conditions using its self-learning function. The PlanetX Sensor must be used with an RJ11 cable and Nezha expansion board.
Specification:
• Connection: RJ11 4P4C
• Connection Type: IIC
• Working Voltage: 3.3V
• Size: 71.79 x 47.9 mm
• Valid Scope: 8~16 mm
Instructions:
To enable line-following functionality, the sensor must first "learn" the background and the path (typically a black line). Follow these steps to complete the learning process:
• Point the probe at the map background and press the "Learn" button.
• The four probe indicator LEDs will light up in sequence, while the two "Learn" indicators flash alternately.
• If the fill light flashes rapidly in multiple colors, move the sensor back and forth horizontally over both the background and the track.
• Continue this motion until the fill light stops flashing—indicating that the learning process is complete.
Note: The ideal distance between the sensor and the surface should be between 8mm and 16mm.
Once learning is completed:
• The two "Learn" indicators will turn off.
• When the sensor detects the track, the corresponding probe indicator will light up.
• If learning fails, both the solid and hollow circle LEDs will flash rapidly, and the fill-light RGB LED will turn off.
