Introduction
This is a multipurpose IR Obstacle sensing module which can be used for sensing obstacles, color detection(between basic contrasting colors), flame or fire detection (uses only receiver LED), line sensing (by bending the module or LED's), etc and also as an encoder sensor. The module provides a logic one(+5V) at the digital output when an object is placed in front of the sensor and a logic zero(0V), when there is no object in front of the module. There are two onboard LED's. One to indicate power and another to indicate the presence of an object. This digital output can be directly connected to an Arduino, Raspberry Pi, AVR, PIC, 8051 or any other microcontroller to read the sensor output.

Note : Infrared Sensors are highly susceptible to ambient light and the IR sensor on this sensor should be suitably covered to reduce effect of ambient light on the sensor. For maximum, range the on board potentiometer should be used to calibrate the sensor. To set the potentiometer, use a screw driver and turn the potentiometer till the output LED just turns off.
