01. SYSTEM OVERVIEW The SB-AT08 is an interactive, computerized automotive training system from SB-TEK. It is modularized for electronic and automotive courses, letting students simulate fuel injection, ignition, and exhaust gas control systems on real automotive circuitry rather than a simplified mock-up. All learning is supported by PC-based supervision and dedicated software (laptop/notebook not included). The system pairs a single-chip microcontroller-based main unit with ten plug-in experiment modules, an integrated TFT display for on-unit process visualization and control, and a built-in web server for remote monitoring, data logging, and trend analysis — giving students a complete path from live sensor measurement to networked data review.
