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

MAX30102 Pulse Oximeter & Heart-Rate Module The MAX30102 is integrated pulse oximetry and heart-rate monitor biosensor module. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The MAX30102 provides a complete system solution to ease the design-in process for mobile and wearable devices. The MAX30102 operates on a single 1.8V power supply and a separate 5.0V power supply for the internal LEDs. Communication is through a standard I2C-compatible interface. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all times.
