LSS05 (Low cost line sensor bar) consists of 5 IR transmitter and IR receiver pairs.
LSS05 is the typically used for embedded system or robots in line following task. LSS05 can
be used for either dark or bright line following. Any color with distinct brightness difference
is suitable for LSS05.
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.
LSS05 have 5 digital outputs to user indicating the existence of the line. The
threshold to the brightness of line existence will be set when the user calibrate the sensor to
the surface that it will recognize. One digital input of calibration signal is available to user for
automated calibration function by the user system. User can pull down this signal line with
microcontroller to calibrate the sensors. This signal line also can be use to enter different
mode of LSS05. Each sensor of the 5 sensors on LSS05 is independent of each other. The
refreshing rate of the sensors is more than 100Hz. Every sensor is provided with its own
LEDs as indication of line detection.
LSS05 has a manual calibration button. The calibration button is multifunctional.
User can enter different mode of functions using calibration button too as the alternative to
the calibration signal.
Note: Red color is very bright to IR sensor, thus LSS05 has difficulties in red – white pair
color line follow.
