MAX 30102

MAX30102 ek advanced biometric sensor module hai jo Heart Rate (Pulse) aur Blood Oxygen Level (SpO₂) measure karta hai. Ye MAX30100 se better performance deta hai (better accuracy + noise handling), isliye health monitoring aur wearable projects me bahut popular hai.

✅ Key Features

• Sensor IC: MAX30102

• Measures: Heart Rate + SpO₂

• Interface: I2C (SDA / SCL)

• Operating Voltage: 1.8V (chip) + 3.3V (module support)
  (Most modules VCC input 3.3V / 5V support karte hain)

• Built-in LEDs: Red LED + IR LED

• Low Power: Wearable applications friendly

• Better Signal Quality: Improved noise rejection (vs MAX30100)
