A Non-Invasive Cholesterol Measuring Device Using a Photodiode Sensor With a BLYNK Interface

Degenerative disease affects the central nervous system, bones and joints, blood vessels, and heart and is caused by the degeneration of a tissue or organ system over time. Cholesterol is a naturally occurring chemical that has the physical properties of fat but a steroidal composition. Cholesterol is routinely created in the proper amounts by the body. Normal cholesterol levels in the body can be restored by utilizing the Easy Touch GCU device, which can be bought conveniently and inexpensively. Its use, however, necessitates the assistance of medical specialists. Non-invasive procedures, for example, have been widely developed in the development of measuring equipment or detection of cholesterol levels. Using infrared light (NIR) and lasers, non-invasive techniques of detecting cholesterol levels have been developed. Designing block. Diagrams, power supply circuits, light source circuits, photoresistor transducer circuits, Arduino microcontrollers, and software on mobile _phones are all part of the design and construction of a cholesterol measurement device. To. test this module experimentally, compare the cholesterol monitoring module created with_ the gold standard. 'The findings demonstrate _that non-invasive level monitoring is a measurement of accuracy and error measurement. The error of measuring cholesterol in the blood using a module with a non-invasive method is 1.46%, with an accuracy of 98.54%. In the future, a non-invasive deep cholesterol measuring device des-igned in research can reduce medical-waste 'and be more convenient to use. The design of non-invasive cholesterol is expected to be able to quickly evaluate cholesterol levels.
