🔌 Wiring Guide – Arduino Integration

This I²C sensor connects easily with Arduino:

Board PinArduino Pin
VCC3.3 V or 5 V (if breakout has level shifter)
GNDGND
SDAA4 (UNO/Nano) or SDA pin (others)
SCLA5 or SCL pin

No additional pull-ups needed on breakout versions.

📚 Library Integration

Example Sketch:

cpp
CopyEdit
#include <Wire.h>
#include <Protocentral_MAX30205.h>

MAX30205 tempSensor;
void setup(){
  Serial.begin(9600);
  tempSensor.begin(); // I2C init
}

void loop(){
  float t = tempSensor.readTemperature();
  Serial.print("Temp: ");
  Serial.print(t);
  Serial.println(" °C");
  delay(1000);
}

This reads precise temperature to ±0.1 °C resolution.
