Infrared sensor module for obstacle avoidance

Model: E3L1C2.
Infrared sensor module for obstacle avoidance.
The sensor module adaptable to ambient light; It has a pair of infrared emitting and receiving tubes, the transmitting tubes emit a certain infrared frequency, when the direction of an obstacle (reflecting surface) is detected, the reflected infrared is received by the receiving tube, after a processing comparator circuit , the green light is on, but the output signal of the digital signal interface (a low-level signal), you can adjust the sensing distance knob potentiometer, the effective distance range of 2 ~ 30cm, the operating voltage of 3.3V - 5V. The detection range of the sensor can be obtained by adjusting the potentiometer, with little interference, easy to assemble, user-friendly functions, can be widely used in robot obstacle avoidance, car evasion, line counting, line tracking in black and white, etc.
