Click MAX30101 High-Sensitivity Pulse Oximeter and Heart ...

1 General DescriptionThe MAX30101 is an integrated Pulse oximetry and Heart -rate monitor module. It includes internal LEDs, photode-tectors, optical elements, and low-noise electronicswith ambient light rejection. The MAX30101 provides acomplete system solution to ease the design-in processfor mobile and wearable MAX30101 operates on a single power supplyand a separate power supply for the internal is through a standard I2C-compatibleinterface. The module can be shut down through softwarewith zero standby current, allowing the power rails toremain powered at all Wearable Devices Fitness Assistant Devices Smartphones TabletsBenefits and Features Heart -Rate Monitor and Pulse Oximeter Sensor inLED Reflective Solution Tiny x x 14-Pin Optical Module Integrated Cover Glass for Optimal, RobustPerformance Ultra-Low-Power Operation for Mobile Devices Programmable Sample Rate and LED Current forPower Savings Low-Power Heart -Rate Monitor (< 1mW) Ultra-Low Shutdown Current ( A, typ)
