em7028 series is a low-power i2cinterfacemodule includes heart rate sensor(hrs) and internal led current drivers with 2green led.it can work in both continuous mode and pulse mode. it is designed for applications ofheart beat rate detection esp. such as smart watch etc.
heart rate sensor in continuous mode is designed to monitor heart rate by optical detection. a 16-bit adc detects the resultconstantlywith adjustable gain and resolution.
heart rate sensor in pulse mode is designedtomonitor heart rate by optical detection in low-power. it also  acts as a proximity sensor with rejection of ambient light noise. in order to removing component variations and eliminateoffsetcaused by ir reflection, 2 registers were specially defined for compensation andhighdynamic range of detection.
hrs in continuous mode stores adc outputresultinto hrs1 registers, while hrs in pulse mode stores adc output result into hrs2 registers. all pixels are controlled by analog-mux in different modes.
