Arduino I/R Reflective Switch Module
This module uses a infrared sensor containing an emitter along with a detector to sense objects or surfaces. The I/R receiver is connected to a LM393 voltage comparator with adjustable sensitivity control (R6). Module has a LED indicator that turns on when it receives a reflection from the IR emitter. The output can be connected directly to a micro-controller I/O port. Ideal for line following robots, collision avoidance & counting passing objects.
Power: 3.3V to 5VDC
Supply Current: < 40mA (LED off)
Sense Range: 10-30+cm Depending on reflectiveness of object
Sense Angle: ~ 20deg.
Output: Digital TTL Open Collector Current sink 20mA
