IoT Based Dipstick Type Engine Oil Level and Impurities Monitoring System: A Portable Online Spectrophotometer

The paper describes the design and development of an IoT based oil impurities, level monitoring instrument and its operational methodology. The research work uses a unique approach with customized white LED spectrophotometry. The developed instrument has done Qualitative and Quantitative assessment of lubricant oil in IC engine's sump. This in turn is helpful in carrying out decisive task towards maintaining Engine life cycle and carbon footprint. Light-dependent sensor with sensitivity <;90% and range 500-600nm is used as a detector for experimentation on four stroke IC Engine. The system has advantages of affordability and portable design.
