OIL PURITY CHECKING IN AUTOMOBILES

Purity in engine oil ensures proper working of engine. Degradation in purity will gradually decrease performance of vehicle and further degradation may completely damage engine.To avoid this, engine oil is changed in particular interval of kilometer.

Even in this case some times it happens to change engine oil after degrading in its quality. This situation can be avoided if we can change engine oil basins on its quality rather than kilometers travelled and arbitrary check engine oil purity indication system dynamically.

This project involves optical sensor( IR-PHOTO DIODE pair) to indicate purity level comparator for setting different levels of purity by user to get indicated on purity level.

Micro controller(AT89C2051) is used to collect sensor data an indicate it through LEDs for level of purity.
