ams AS7057
The AS7057 Biosignal Sensor Analog Frontend (AFE) is the next generation Vital Sign Sensor. It enables the user to detect biosignals such as photoplethysmogram (PPG) and pulse transit time (PTT), as well as proximity. It measures the pulse rate - by sampling light modulated by the blood vessels, which expand and contract as blood pulses through them.GENERAL DESCRIPTION

GENERAL DESCRIPTION
1GENERAL DESCRIPTION
PPG is the most used HRM method. Apart from HRM/HRV, optical Blood Pressure and SpO2 are also enabled by the two independent working photodiode inputs of the AS7057. The AS7057 is a size and performance optimized analog frontend to support space-limited applications such as in-ear vital sign monitoring.
