The Grove – Finger-clip Heart Rate Sensor with shell is based on PAH8001EI-2G; a high-performance and low-power CMOS optical sensor with integrated DSP and an LED that serve as a heart rate detection (HRD) sensor. This module is based on optical technology which measures the blood movement in the wearer. This module has a low power consumption and a flexible power-saving mode that makes it suitable for wearing on a finger/arm (this item also comes with tow bandages and a shell for this purpose). Due to the high processing speed needed for the algorithm, STM32 is integrated with this module and the SWD interface allows users to reprogram the STM32.

• Ultra-low power consumption power saving mode during time of no touch movement
• With tow bandages and 3D printing shell
