Circuit Setup

1. Connect the glucose sensor’s VCC and GND to the 5V and GND on Arduino.
2. Connect the output pin of the glucose sensor to an analog input pin (e.g., A0) on Arduino.

The glucose sensor will measure the glucose concentration and output an analog signal to Arduino.

Code for Glucose Detection

Upload the following code to your Arduino to detect glucose concentration:

const int glucosePin = A0;

void setup() {
  Serial.begin(9600);
}

void loop() {
  int glucoseLevel = analogRead(glucosePin);
  Serial.print("Glucose Concentration: ");
  Serial.println(glucoseLevel);
  delay(1000);
}
            

Explanation

The glucose sensor measures the concentration of glucose in a sample and sends an analog signal to the Arduino, which then displays the result on the Serial Monitor.

Troubleshooting

• Check the sensor's calibration if readings are incorrect.
• Ensure that the sensor is connected properly to the Arduino.
