Product Description:

Feature:

1. It uses standard I2C compatible communication interface, and can transmit the collected values to single-chip computer for heart rate & oxygen calculation.
2. It can effectively eliminate the external and internal light resistance and has reliable performance.
3. It can shut down the module through software ,the standby current is close to zero, and the power supply can always maintain the power supply state.
4. It integrates a red LED and an infrared LED, photo detector, optical devices, and low-noise electronic circuit with ambient light suppression.
5. VIN: Main power input 1.8V-5V
