MAX30100 Heart Rate and Heart Rate Sensor Module

MAX30100 Pulse and Heart Rate Sensor Module

This product carries Maxim's MAX30100 integrated pulse oximeter and heart rate sensor. It is an optical sensor that receives the readings from emitting two wavelengths of light from two LEDs (red and infrared) and then measures its absorption in the bloodstream against a photodetector.

This particular LED color combination is optimized for fingertip reading data. The signal is processed by a low noise analog signal processing unit and transmitted to the target MCU via the microBUS I2C interface. Developers of end-user applications should be aware that readings can be adversely affected by extreme movement and temperature changes. Also, too much pressure can limit capillary blood flow and therefore reduce the reliability of the data. A programmable INT pin is also available.

Uses 3.3V power supply.
