This module can be used as line sensing, light or fire sensor. It can also be used for line following purpose and obstacle detection. IR LED in the circuit emits IR rays. When an object or white surface comes in front of the module, some rays are reflected back and are collected by the photodiode. A NPN Bipolar transistor is used as a switch to provide the digital output. If the module is used as light or fire sensor, photodiode will detect the IR Rays generated by light or fire. This module provides both analog and digital output.
