System Overview

components and how they work with the chip.

The PAH8011ES is based on CMOS optical technology and designed to meet the requirements for the implementation in

heart rate monitor accessories and wearables like smart watch or wrist band device. Figure 5 illustrates a system design for

App Level diagram. The processor is accessing PPG data from the chip, then pass it to App level. APP level applies PixArt

provided algorithm library to determine the heart rate data and waveform. Figure 6. System Design for Firmware Level

illustrates a system design for Firmware Level diagram. The processor will also access PPG data from the chip, then perform

heart rate calculation with PixArt algorithm library and send result to display or end device.

PAH8011ES can be configured to generate different frame rate setting.
