Features 1.Reliable Use: With infrared distance detection sensor and touch detection sensor, the robot you designed can adapt to more situation. 2.Line Sensing: Has 6 way high sensitivity infrared sensors, 5 way patrol lines and 1 way for road barrier, which can easily identify and track complex and intersecting black and white lines. Output low level for black output and high level for white line. 3.Smart Design: Integrates an infrared obstacle avoidance sensor and a touch detection sensor, the obstacle avoidance distance can be adjusted between 0‑10CM through a rheostat, and output a high level when there is an obstacle. 4.Easy Debugging: All sensor output states are indicated by LED lights, which is convenient for debugging. 5.Simpler Wiring: The sensors are reasonably arranged on one module, and there is no need for more lines when connecting, which reduces the probability of errors. Specification Item Type: Infrared Sensor Module Input Voltage: 3.0-5.5V Tracking Distance: Approx. 0 ~ 3cm / 0 ~ 1.18in (black and white line sensor) Barrier Distance: Approx. 0 ~ 6cm / 0 ~ 2.36in (adjustable detection distance) Output Form: High and low level signal.
