Si1144

Optical Heart Rate Sensor Module with I²C Interface and HR Measurement Software

Silicon Labs

The Si1144-AAGX is a low-power, reflectance-based, heart rate sensor. This optical heart rate sensor module includes an analog-to- digital converter, integrated high-sensitivity photodiodes, host communications processor, a green high efficiency LED, and three integrated LED drivers with ninety selectable drive levels. The Si1144-AAGX offers excellent performance under a wide dynamic range and a variety of light sources from 525nm to 940nm. The Si1144-AAGX devices are provided in a 10-lead 4.9 x 2.85 x 1.2 mm LGA module package and are capable of operation from 1.71 to 3.6 V over the –40°C to +85°C temperature range.
