# Arduino blood glucose meter shield ## Description 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. ## Project Details - **Owner:** oozliuoo - **Created:** 8/20/2021 - **Last Updated:** 8/20/2021 - **Visibility:** Public - **:** https://hackaday.io/project/11719-open-source-arduino-blood-glucose-meter-shield ## Key Components ### ? — [TPS76901DBVT](https://www.flux.ai/ramprakashvishnoi8/tps76901dbvt.md) **Pins:** - ~EN - GND - IN - NC/FB - OUT ### ? — [TPS76925DBVT](https://www.flux.ai/ramprakashvishnoi8/tps76925dbvt.md) **Pins:** - ~EN - GND - IN - NC/FB - OUT ### ? — [CD4066](https://www.flux.ai/ramprakashvishnoi8/cd4066.md) **Pins:** - CONT1 - CONT2 - CONT3 - CONT4 - IN/OUT 1 - IN/OUT 3 - IN/OUT 4 - IN/OUT2 - OUT/IN 1 - OUT/IN 2 - OUT/IN 3 - OUT/IN 4 - VDO - VSS ### ? — [Arduino Nano 33 BLE](https://www.flux.ai/jharwinbarrozo/arduino-nano-33-ble.md) - Manufacturer Part Number: ABX00030 **Pins:** - +5V - 3V3 - A0 - A1 - A2 - A3 - A4 - A5 - A6 - A7 - AREF - D10 - D11 - D12 - D13 - D2 - D3 - D4 - D5 - D6 - D7 - D8 - D9 - GND - GND - RESET - RESET - RX - TX - VIN ### +2V1 — Label **Pins:** - P1 - P2 ### +2V5 — Label **Pins:** - P1 - P2 ### +2V5 — Label **Pins:** - P1 - P2 ### +2V5 — Label **Pins:** - P1 - P2 ### +5V — [Power Symbol](https://www.flux.ai/usairemalamgeer/power-symbol.md) **Pins:** - P1 ### +5V — [Power Symbol](https://www.flux.ai/usairemalamgeer/power-symbol.md) **Pins:** - P1 ### +5V — [Power Symbol](https://www.flux.ai/usairemalamgeer/power-symbol.md) **Pins:** - P1 ### +5V — [Power Symbol](https://www.flux.ai/usairemalamgeer/power-symbol.md) **Pins:** - P1 ### +5V — [Power Symbol](https://www.flux.ai/usairemalamgeer/power-symbol.md) **Pins:** - P1 ### +5V — [Power Symbol](https://www.flux.ai/usairemalamgeer/power-symbol.md) **Pins:** - P1 ### +5V — [Power Symbol](https://www.flux.ai/usairemalamgeer/power-symbol.md) **Pins:** - P1 ### +5V — [Power Symbol](https://www.flux.ai/usairemalamgeer/power-symbol.md) **Pins:** - P1 ### 1500 — [Fixed Resistor](https://www.flux.ai/lwcassid/fixed-resistor.md) - Resistance: 500Ω - Resistance: 500Ω - Part Type: Resistor **Pins:** - P1 - P2 ### 5V Li ion battery — Multi Cell Battery - Number of Cell: 2 - Max Voltage per cell: +5V **Pins:** - ANODE - CATHODE ### ADC 0 — Label **Pins:** - P1 - P2 ### ADC 0 — Label **Pins:** - P1 - P2 ### ADC 1 — Label **Pins:** - P1 - P2 ### ADC 1 — Label **Pins:** - P1 - P2 ### D5 — Label **Pins:** - P1 - P2 ### D5 — Label **Pins:** - P1 - P2 ### D6 — [LED](https://www.flux.ai/jharwinbarrozo/led-tht.md) - Series Resistance: 0.42Ω - Saturation Current: 93.2e-12A - Forward Voltage: 1.70 - Breakdown Voltage: 0V - Emission Coefficient: 3.73 **Pins:** - ANODE - CATHODE ### IN/OUT1 — Label **Pins:** - P1 - P2 ### IN/OUT1 — Label **Pins:** - P1 - P2 ### LMC6484 IC_B — LMC6484 IC_B - Part Type: Operational Amplifier (OP-AMP) **Pins:** - 5 - 6 - 7 ### LMC6484 IC_C — [LMC6484 IC_C](https://www.flux.ai/ramprakashvishnoi8/lmc6484-icc.md) - : LMC6484 - Package or Case Code: 14-SOIC (0.154", 3.90mm Width) - Manufacturer Part Number: LMC6484_C - DataSheet URL: https://www.ti.com/general/docs/suppproductinfo.tsp?distId=10&gotoUrl=https%3A%2F%2Fwww.ti.com%2Flit%2Fgpn%2Flmc6484 - Manufacturer Name: Texas Instruments - Part Type: Operational Amplifier (OP-AMP) **Pins:** - 10 - 8 - 9 ### LMC6484 IC_D — LMC6484 IC_D - Part Type: Operational Amplifier (OP-AMP) - Manufacturer Part Number: LMC6484_D **Pins:** - 12 - 13 - 14 ### OUT/IN1 — Label **Pins:** - P1 - P2 ### OUT/IN1 — Label **Pins:** - P1 - P2 ### STRIP_DETECT — Label **Pins:** - P1 - P2 ### Working electrode — Label **Pins:** - P1 - P2 *The full schematic, PCB layout, bill of materials, and interactive design are available at [https://www.flux.ai/oozliuoo/arduino-blood-glucose-meter-shield](https://www.flux.ai/oozliuoo/arduino-blood-glucose-meter-shield).* --- *Generated from [https://www.flux.ai/oozliuoo/arduino-blood-glucose-meter-shield](https://www.flux.ai/oozliuoo/arduino-blood-glucose-meter-shield)*
