Grove - Finger-clip Heart Rate Sensor with shell Grove - Finger-clip Heart Rate Sensor with shell is based on PAH8001EI-2G, a high performance and low power CMOS-process optical sensor with Green LED and DSP integrated serving as a Heart Rate Detection (HRD) sensor.This module is based on optical technology which measures the variation human blood movement in the vessel. Low power consumption and flexible power saving mode make it suitable for wearable device. Cause the heart rate sensor chip need high processing speed for the algorithm of heart rate data, this module integrate a STM32, reserved SWD interface allow users to reprogram the STM32. This module equips a shell and two bands that allow users to fix the module on finger, wrist or arm easily. Specification Ultra-low power consumption, power saving mode during time of no touch movement Flexible sleep rate control Integrated the STM32F103 I2C interface Heart rate sensor area just 3.0 x 4.7mm Reserved SWD interface equip with shell and bands Working temperature: -20 to +60 Interface Function 1: Grove Interface 2: Reserved SWD Interface for programming to STM32 3: Heart Rate Sensor Usage Here, We will provide an example here to show you how to use this sensor.
