Description

• It is an integrated pulse oximetry and heart rate monitor sensor solution
• Integrated LEDs, Photo Sensor, and High-Performance Analog Front -End
• Complete Pulse Oximeter and Heart-Rate Sensor Solution Simplifies Design
• Measures absorbance of pulsing blood
• Ultra-Low-Power Operation Increases Battery Life for Wearable Devices

The MAX30102 Pulse Oximeter Heart-Rate Sensor Module I2C Interface 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. The heart rate oximetry module made with the MAX30102 is an upgraded version of the MAX30100 that can be used to measure heart rate oximetry on the wrist. It can be applied to smart wear fields such as sports watches. MAX30102 is an integrated pulse oximeter and heart-rate monitor sensor solution. Its an optical sensor that derives its readings from emitting two wavelengths of light from two LEDs a red and an infrared one then measuring the absorbance of pulsing blood through a photodetector. This particular LED colour combination is optimized for reading the data through the tip of ones finger. It is fully configurable through software registers and the digital output data is stored in a 16-deep FIFO within the device.It has an I2C digital interface to communicate with a host microcontroller. The pulse oximetry subsystem in MAX30102 consists of ambient light cancellation (ALC), 16-bit sigma delta ADC, and proprietary discrete time filter. It has an ultra-low-power operation which makes it ideal for battery operated systems. MAX30100 operates on a supply in the range of 1.8 to 3.3V.It can be used in wearable devices, fitness assistant devices, medical monitoring devices, etc.The MAX30102 operates from 1.8V and 3.3V power supplies and can be powered down through software with negligible standby current, permitting the power supply to remain connected at all times.
