This Line Tracking Sensor can detect white lines in black background and black lines in white background. The single line-tracking signal provides a stable output signal TTL for a more accurate and more stable line. Multi-channel option can be easily achieved by installing required line-tracking robot sensors.
Power supply: +5V
Operating current: <10mA
Operating temperature range: 0°C ~ + 50°C
Output interface: 3-wire interface (1 - signal, 2 - power, 3 - power supply negative)
Output Level: TTL level
void setup()
{
Serial.begin(9600);
}
void loop()
{
