Cytron Technologies LSA08 Line Following Sensor Bar User’s Manual

Below you will find brief information for Line Following Sensor Bar LSA08. The LSA08 is a line following sensor bar that consists of 8 IR transmitter and IR receiver pairs. It can detect any color of line which has brightness different with the background. The IR transmitters on LSA08 are pulsed to allow the transmitter to off at certain idle period of sensor. This minimizes the current consumption of LSA08 to at least half of the current consumption compared to a normal unregulated IR line sensor. Power polarity protection is available on LSA08 in case the user accidentally applies a reverse voltage.

Frequently asked questions

The LSA08 is a line following sensor bar used for embedded systems and robots to detect and follow lines of varying colors.

The LSA08 uses 8 IR transmitter and receiver pairs to detect the difference in brightness between the line and its background.

The LSA08 offers three output modes: digital, UART (serial communication), and analog. The digital output provides 8 parallel lines indicating line detection, while the UART provides data in various formats, and the analog output provides a voltage proportional to the line position.

Calibration is necessary to establish the brightness values of the line and background. You can do this using the 'CALB' menu on the internal LCD, exposing the sensors to the dark and bright surfaces within a designated timeframe.

The maximum operating voltage of the LSA08 is 12V.

The maximum sensing distance from the board is 5 cm.

You can connect the LSA08 to a microcontroller or computer using the UART pins. By sending specific commands through the UART, you can control the LSA08's settings and retrieve data like sensor readings or line position.
