1. INTRODUCTION AND OVERVIEW
LSA08 (Advance Line Following Sensor Bar) consists of 8 sensors pair. LSA08 is
typically used for embedded system or robots for line following task. LSA08 can detect any
color of line which has brightness different with the background. LSA08 is capable to operate
on surface with color of Red, Green, Blue, White, Black, Gray and possibly other colors
which are not listed.
LSA08 has some special features which give advantages to the user. LSA08 has low
current consumption, typically around 26mA. Power polarity protection on LSA08 prevents
damage by applying reversed voltage. LSA08 provides multiple interface methods, namely
serial (UART), analog output and direct digital outputs (parallel output). LSA08 has total of 8
sensors spaced at 16mm. This minimizes the user effort of setup the sensor system for the
line following robot. Besides, LSA08 has LCD which displays the sensors and line
information. This LCD together with setting buttons (SEL and MODE) also enables instant
setting up of LSA08. Auto calibration feature of LSA08 calibrates the sensors to the line and
background surface easily. Furthermore, LSA08 with special selected transmitters and
receivers sensor is capable to work on reflective or glossy surface which is difficult to
normal infrared (IR) sensor.
