Si1143/44 Heart Rate Monitoring Solution
The Silicon Labs Si1143/44 solution combines a high-precision optical sensor, an LED source, a proprietary algorithm, and a low power MCU to deliver a low power, dynamic heart rate monitoring (HRM) solution. Target markets include fitness bands, smart watches, and consumer health applications.
The Si1143/44 uses a single green LED, which allows it to be packaged in an exceptionally small package (2.9 mm x 4.9 mm), and delivers great performance at a low cost and size.
