Abstract

There are several problems and worries associated with the concentration level of coconut oil. Because solvent-based chemical extraction methods have the potential to leave residues and endanger both human health and the environment, they could be problematic. The production of RBD coconut oil serves as an example of how nutrients and antioxidants found in unrefined varieties may be lost during the refining process. Since there has been adulteration in the industry, purity and quality are essential. Waste disposal is one example of an environmental effect that needs to be carefully considered. In addition, the need for sustainable methods and consumer preferences for virgin coconut oil highlight the importance of ethical sourcing and processing. In the coconut oil industry, label transparency, avoiding misleading claims, and maintaining the nutritional value and oxidative stability of concentrated products are all necessary to meet consumer expectations. Thus, the goal of the project is to create a level sensor for coconut oil concentration level using green LED detection.The purpose of this project is to develop an LDR oil concentration level sensor, analyse its performance using green LED power transfer, and optimise its performance based on results related to sensitivity, linearity, and stability.An Arduino UNO processor is used to measure the coconut oil concentration level and controls the system's inputs and outputs. It controls the green LED's functionality, including turning it on and off. To enable observation, the Arduino UNO transmits data to the LCD regarding the amount of light reflected from the oil samples. The sensor that measured light intensity as it passed through the oil is called an LDR.Consequently, three types of graphs demonstrating linearity, repeatability, and stability have been created along with a sensitivity value. It demonstrates that light emitted from oil decreases with increasing salt concentration level.With little expense and user effort, this invention offers a better understanding of coconut oil in the food industries.
