4-Bit Line Hunting Sensor Follower Module for Arduino
Price in Sri Lanka

Applications:

• Smart car or a robot hunt (including black and white lines), walking path along the black line, also known as tracking.
• Smart car to avoid obstacle and cliff, anti-drop.
• Can be applied to other automation applications of photoelectric reflex.

Specification:

• Working voltage: DC 3.3V-5V
• Working current: try to choose more than 1A power supply
• Working temperature: -10°C to +50°C
• Detection range: 1mm to 60cm adjustable, the closer the performance more stable, white reflects the farthest distance.
• The output signal: TTL level (can be directly connected to I/0 microcontroller, infrared light reflected back to the sensor induction, the red indicator light, output low level; no infrared light, the indicator light does not shine, the output high.)
