The 8 Channel Saleng Tracker Module is an array of 8
infrared sensors designed for line or simple color
sensing and general purpose proximity sensing. An on
board RISC processor takes care of all sensor processing
and therefore lessens software load on the main host. There are two concurrent interface ports: a serial (UART) and parallel output ports, one for each sensorelement. The module uses infrared elements that come with built-in sunlight filter providing improved performance in sunlit areas than traditional photodiodes.
