This module is an integrated pulse oximeter and heart rate monitor sensor solution. It combines two LEDs, a photodetector, optimized optics, and low-noise analog signal processing to detect pulse oximetry and heart-rate signals.

• Supply Voltage: 3.3V~5V
• Detect distance: Skin contact, optical
• Detects heart pulses and blood oxygen level by measuring IR and Red light reflected level.
• Measures Temperature.
• Data interface : I2C (Require pull up for full speed operation)
• Pins : Vcc, Int , IR_D , Red_D, SCL, SDA, Gnd
• Connect VCC, Gnd , SCL , and SDA to operate the module.
