em7029 series is a low-power i2c interface module includes heart rate sensor(hrs) and internal led current drivers with 2 green led. it can work inbothcontinuous mode and pulse mode. it is designed for applications of heart beat rate detection esp. such as smart watch etc.
heart ratesensorin continuous mode is designed to monitor heartrateby optical detection. a 16-bit adc detects the result constantly with adjustable gain and resolution.
heart rate sensor inpulsemode is designed to monitor 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 componentvariations andeliminate offset caused by ir reflection, 2 registers were specially defined for compensation and high dynamic range of detection.
hrs in continuous modestoresadc output result into hrs1 registers, while hrs in pulse mode stores adc output result into hrs2 registers. all pixels are controlled by analog-mux in different modes.
