Description:
This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of leds are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be turned off for additional sensing or power-savings options. Each sensor provides a separate digital I/O-measurable output. This reflection sensor array is intended as a line sensor, but it can be used as a general-purpose proximity or reflection sensor. The module is a convenient carrier for eight IR emitter and receiver (photo-transistor) pairs evenly spaced at intervals of 0.375″ (9.525?mm). Each photo transistor is connected to a pull-up resistor to form a voltage divider that produces an analog voltage output between 0?V and VIN (which is typically 5?V) as a function of the reflected IR. The lower output voltage is an indication of greater reflection.
