Mikroe Heart Rate 2 Click

Mikroe Heart Rate 2 Click features an Analog Devices / Maxim Integrated MAXM86161 optical data acquisition system ideal for optical pulse oximetry and heart-rate detection applications. The optical readout has a low-noise signal conditioning analog front end (AFE). The device includes a 19-bit ADC, an industry-lead ambient light cancellation (ALC) circuit, and a picket fence detect-and-replace algorithm. The system includes high-resolution optical readout signal processing channels with robust ambient light cancellation.
