-The %%Pmod LS1%% is designed to be used with up to four sensors containing an infrared %%LED%% and an infrared-sensitive photo-transistor, such as the [[http://store.digilentinc.com/ir-proximity-sensor-2-pack/|IR Proximity Sensor available from Digilent]]. When using Digilent’s sensors, refer to the print on the board indicating the wire color for the correct orientation of the wire. If third-party sensors are used, refer to the  board schematic available at [[http://www.digilentinc.com/Data/Products/PMOD-LS1/PmodLS1_sch.pdf|www.digilentinc.com]] for the proper connection of the %%LED%% and photo-transistor. +The %%Pmod LS1%% is designed to be used with up to four sensors containing an infrared %%LED%% and an infrared-sensitive photo-transistor, such as the [[https://digilent.com/shop/ir-proximity-sensor-2-pack/|IR Proximity Sensor available from Digilent]].

 The module uses analog comparators to determine when the infrared detectors have sensed more infrared light than the threshold limit. The sensitivity of the sensors can be adjusted by adjusting the onboard potentiometer.  The module uses analog comparators to determine when the infrared detectors have sensed more infrared light than the threshold limit.
