Integrates a red LED, a infrared LED, aphotodetector, an optical equipment and a low noise electronic circuit with environmental light suppression.
The standard I2C compatible communication interface can transmit the collected data to Arduino, KL25Z and other microcontrollers for heart rate and blood oxygen calculation.
Apply to wearable device for heart rate and blood oxygen collection, worn on fingers, ear lobes, wrists and other places.
The chip can also turn off the module by software, and the standby current is close to zero, so that the power supply can always be maintained.
