Detection of Glucose Using Non-Invasive Method and Food Analysis for Diabetic Patients Using IoT

In current trends of smart wearables, there are lot of smart devices for healthcare systems. Among them the detection of Glucose from the patient is tested using blood sample by pricking the finger. This paper demonstrates a device to test the blood glucose level using non-invasive method of not pricking the finger. A Node MCU 32S is used as microcontroller to obtain the readings from the blood glucose detector, temperature sensor and heart rate sensor. The Glucose detector contains PIC16LF178X chip and has two electrodes to send and receive data bits. The electrodes are placed on the tongue where one electrode sends a certain bit of data. The data bits when passed through the blood in the tongue, certain amount is lost due to the presence of glucose. The remaining bits are detected at the second electrode. The difference between these values gives the amount of glucose in the blood. The temperature sensor detects body temperature. The pulse sensor detects the heart rate and blood pressure. These readings are displayed on the mobile application which is connected to the microcontroller via interne. Based on these readings, the microcontroller sends alerts in the mobile application. The dietary suggestions are given to the patient through the mobile application in order to maintain normal glucose levels and also to reduce in times of high glucose levels. A list of foods which should be taken is displayed on the mobile application
