Heart rate module is adaptable for different lighting conditions or skin tones

MikroElektronika MIKROE-2036 Heart rate 3 click, available from Mouser, is a mikroBUS add-on board with an OSRAM SFH7050 heart rate module and a TI AFE4404 analong-front-end IC. The SFH7050 multichip package contains three LEDs and one photodiode separated with a light barrier to prevent optical crosstalk. The IC is adaptable for different lighting conditions or skin tones making the Heart rate 3 click a robust heart rate monitoring solution. The board uses the mikroBUS I2C interface to communicate with a target MCU. Additional functionality is provided by RST, CLK and RDY pins. Heart rate 3 click works with a 3.3V power supply and an onboard jumper allows for driving the LEDs at either 3.3V or 5V.
