سنسور MAX30102 با ولتاژ 1.8 ولتی کار کرده و ولتاژ LED های داخلی آن توسط یک منبع جداگانه 3.3 ولتی تامین می شود. ارتباط آن از طریق پروتکل I2C است. همچنین برای صرفه جویی در مصرف انرژی می توان به صورت نرم افزاری سنسور را خاموش کرد.
Description:
The MAX30102 is an integrated pulse oximetry and heart-rate monitor module. It includes internal LEDs, photodetectors, optical elements, and low-noise electronics with ambient light rejection. The MAX30102 provides a complete system solution to ease the design-in process for mobile and wearable devices. The MAX30102 operates on a single 1.8V power supply and a separate 3.3V power supply for the internal LEDs. Communication is through a standard I2C-compatible interface. The module can be shut down through software with zero standby current, allowing the power rails to remain powered at all times.
