Page 3: Introduction And Overview
The IR transmitters on LSS05 are pulsed to allow the transmitter to off at certain idle period of sensor. This is to minimize the current consumption of LSS05 to at least half of the current consumption compared to a normal unregulated IR line sensor. Power polarity protection is available on LSS05 in case the user accidently applies a reverse voltage.

Press twice to set the line sensor bar into dark line following mode and press 3 times to set the line sensor bar into bright line mode. C – Mode indicator LED (orange) is for indication of the mode. LED will light up if LSS05 is in bright line detection mode. Otherwise, it is off.

5.1 LSS05 to Mini Mobile Robot Controller (MC40A) Example application of LSS05 is in MC40A. Used as line detection, LSS05 is usually mounted at the bottom of the mobile robot. Created by Cytron Technologies Sdn. Bhd. – All Rights Reserved...
Page 9 Pin pitch for 2020H connector is not standard size for donut board pin pitch. To use LSS05 with donut board, simply cut the end of connector and solder another type of connector like 2510 or 3960 connector.

Every of the IR sensor pairs need to be exposed to the dark and bright surface for it to read the value and save it. LSS05 will save the value in EEPROM, it will retrieve back the data from the EEPROM every time its switch on. Hence, only one time calibration is needed for the same surface and line.
Page 14 Dark/Bright indicator (D/B) indicator LED will light up in orange color for this mode. Below are examples of LSS05 output when it detects dark and bright line. Output 1 is for DS1, output 2 for DS2 and output 3,4, and 5 for DS3,DS4 and DS5 respectively. LED ON means that the sensor detected the line.
Page 15 • One falling edge pulse for calibration mode as shown in figure below. After the falling edge pulse the sensor will start calibration. • Two falling edges for setting the LSS05 into dark line mode. The 2 falling edges need to be in range of 1.5 seconds.
Page 16 The Calibration signal pin has the same functions as the Cal button. Instead of manually pushing the Cal button for the settings of LSS05, user can use a microcontroller to pull down the signal to get into the settings. It is similar to the Cal...
