Glucose meter is a medical device that determines the approximate concentration of glucose in the blood. A strip containing chemicals that react with glucose in the drop of blood is used for each measurement. Op Amp Circuit description: LMC6484 IC_D is an integrator circuit. LMC6484 IC_A and IC_C are configured as unity gain buffer amplifiers. LMC6484 IC1B is configured as a trans impedance amplifier. Arduino is used for processing of the measured glucose level. The Arduino use the built in ADC module for analog to digital conversion. Further, the Arduino helps to detect the strip also.
