Design And Development Of A Microcontroller Based System For The Measurement Of Blood Glucose

摘要

Diabetes Mellitus is a group of metabolic diseases characterized by high blood sugar (glucose) levels which results from defects in insulin secretion. In the present study, a microcontroller based system for the measurement of blood glucose is designed and developed. It is based on the Amperometric method. A PIC 18F4520 microcontroller is used in the present study. LCD module is used to display measured values of blood glucose.The MAX232 is a dual line driver/receiver, converts signals from an RS-232 serial port to TTL compatible signals is interfaced with the microcontroller. Software is developed in C language using MPLAB IDE for the Microchip Technology, due to the inherent language flexibility, the extent of support and its potential for portability across a wide range of hardware. The instrument is tested and results are found to be satisfactory. The instrument is handheld, rugged, low cost, low energy consumption, wearable and cost effective compared to the other commercially available
