MAX30102 Heart Rate and Pulse Oximeter Sensor Module (Black)

MAX30102 Heart Rate and Pulse Oximeter Sensor

Features:

• Optical Heart-Rate Monitor and Pulse Oximetry Solution
• Upgraded version of MAX30100, the MAX30102 has better accuracy and reliability and some new features.
• New features include : Proximity sensing, and better ambient light cancellation.
• Tiny breakout board
• Low power
• Highly-integrated, small-size sensor
• Non-chest based heart-rate/SpO2 detection
• Ultra-low power consumption

Specifications:

• Power supply: 3.3V to 5.5V
• Current draw: ~600μA (during measurements),
• Current draw: ~0.7μA (during standby mode)
• Red LED Wavelength: 660nm
• IR LED Wavelength: 880nm
• Temperature Range: -40˚C to +85˚C
• Temperature Accuracy: ±1˚C

 Pin Configuration:

• VIN is the power pin. You can connect it to 3.3V or 5V output from your Arduino.
• SCL is the I2C clock pin, connect to your Arduino’s I2C clock line.
• SDA is the I2C data pin, connect to your Arduino’s I2C data line.
• INT The MAX30102 can be programmed to generate an interrupt for each pulse. This line is open-drain, so it is pulled HIGH by the onboard resistor. When an interrupt occurs the INT pin goes LOW and stays LOW until the interrupt is cleared.
• IRD The MAX30102 integrates an LED driver to drive LED pulses for SpO2 and HR measurements. Use this if you want to drive the IR LED yourself, otherwise leave it unconnected.
• RD pin is similar to the IRD pin, but is used to drive the Red LED. If you don’t want to drive the red LED yourself, leave it unconnected.
• GND is the ground.

Applications:

• Fitness Assistant Devices
• Medical Monitoring Devices
• Home Heart Rate and SpO2 Monitoring
