Development of Non Invasive Blood Glucose Monitoring

In order to calculate their insulin dosage and make sure their blood glucose level remains within the normal range, diabetics must monitor and measure their blood glucose levels on a frequent basis. It is meant to be possible to test blood glucose levels non-invasively. use a near-infrared (NIR) transmittance spectroscopy without requiring a blood sample, skin puncture, or discomfort. It uses circuits for a light source and a light detector that are placed on the finger. The blood glucose level in that finger area is determined by the detector’s attenuated reception of the infrared light. An IR light source and a receiver module are used in the blood glucose measuring procedure. The receiver measures the changes in light intensity brought on by variations in blood glucose levels when infrared light is delivered through a fingertip and interacts with the blood.A microcontroller NodeMCU receives data received from the receiving circuit and uses it to create mean values and graphs.It is a dependable and easy-to-use tool that can test blood glucose levels precisely without requiring repeated, uncomfortable finger pricks. Individuals can customise their own cutoff points and get notifications when their blood sugar levels deviate from the target range.Users must enter their height and weight into the system’s BMI calculation component in order for it to calculate their BMI.
