Product Description:
The MAX30100 pulse oximeter and heart rate sensor is an I2C-based low-power plug-and-play biometric sensor.
The module features the MAX30100 – a modern, integrated pulse oximeter and heart rate sensor IC, from Analog Devices. It combines two LEDs, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse oximetry (SpO2) and heart rate (HR) signals.
The MAX30100 chip requires two different supply voltages: 1.8V for the IC and 3.3V for the RED and IR LEDs. So the module comes with 3.3V and 1.8V regulators (internally). This allows you to connect the module to any microcontroller with 5V, 3.3V, even 1.8V level I/O.
One of the most important features of the MAX30100 is its low power consumption: the MAX30100 consumes less than 600μA during measurement. Also it is possible to put the MAX30100 in standby mode, where it consumes only 0.7μA. This low power consumption allows implementation in battery powered devices such as handsets, wearables or smart watches.
