Yahboom 4 Channel Infrared Tracking Sensor Module For Smart Car Robot, Spec: With 6Pin Cable+23mm Copper Column
- This tracking module uses four tracking probes and optimizes the spacing layout. The two inner probes can precisely identify the black lines, while the two outer probes can assist the inner probes in identifying the black lines and provide warnings. The vehicle can recognize 90-degree turns and other complex road surfaces.
- The knob-type adjustable resistor is combined with a professional operational amplifier circuit, allowing the adjustment of sensor sensitivity.
- You can connect it to the intelligent car or expansion board using jumper wires or DuPont cables for various experiments. The module is reserved with holes for installing copper columns and screws, making it convenient for you to expand by yourself.
- High-quality infrared probes, with onboard four-channel comparator circuits.
- 1.6-inch thick shock-resistant PCB.
- The module uses 6-pin pins and has an anti-reverse connection design for interfaces, which can effectively prevent positive and negative pole reverse connection and avoid module damage. It is simple and convenient to use.
- High-precision knob adjustment with a wide linear adjustable range.
- Reference materials, driver source code and graphical programming tools are provided.
