Pulse oximeter/heart rate sensor module for wrist-band designs
MAX30102 integrates red and IR LEDs to modulate LED pulses for oxygen saturation (SpO2) and heart rate measurements. It operates on a single 1.8V power supply and a separate 5V power supply for the internal LEDs. The device maintains a very small solution size without sacrificing optical or electrical performance; it integrates internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. An evaluation platform with the integrated module and an accelerometer provides a solution for designers to quickly evaluate the module.
In a 14-pin optical module 5.6 x 3.3 x 1.55 mm, and specified over the -40 to +85C temperature range, pricing starts at $4.13 (1000). An evaluation board is available.
