Infrared emission phototube of each channel sensor is giving off infra-red, when infrared ray is not reflected back or intensity is not enough, the infrared receiving phototube is off, TTL output high level, diodes light is off;
When objection is in the range of detection, infrared ray is reflected back or intensity is enough, TTL output is low level, diodes light is on.
This module is designed for smart car, robot and automated machine
It provides a kind of multifunction infrared detective system for the auto-machine;
This module adopts infrared transmitter & receiver and components as a detector.
