SMAKN&reg; Five Channel Infrared Detection Tracing Photoelectric Sensor Tracking Module BFD-1000 Integrated 5-way tracking sensor with high sensitivity for low environmental impact, able to accurately complex black line (white line) to track, for a simple black line line tracking more ease. BFD-1000 integrates a barrier infrared sensors, unblinded distance can be adjusted by sliding rheostat. BFD-1000 has a specially designed touch detection sensor, making the design more simple from the robot. BFD-1000 all the output signal to a digital signal (high and low), convenient and microcontroller. BFD-1000 has all the sensor output status LED light as indicator for easy debugging.
