EUROPROX Bt.

Gree Online Available in different designs and aspects, the air conditioners are a cheaper option to installing the highly expensive central cooling system. An air conditioner allows you to control the surrounding temperature.

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.
