Silicon Labs (Austin, TX) has introduced the industry’s first single-chip digital ultraviolet (UV) index sensor ICs designed to track UV sun exposure, heart/pulse rate and blood oximetry and provide proximity/gesture control for smartphone and wearable computing products. The latest additions to Silicon Labs’ optical sensor family, the Si1132 and Si114x sensor ICs are ideal for activity-tracking wrist and arm bands, smart watches and smartphone handsets. In addition to enabling UV index sensing, the devices also provide ambient light and infrared (IR) proximity sensing capabilities for health and fitness applications. When combined with an accelerometer, the Si1132 and Si114x sensors:
- Enable developers to implement sleep tracking in wearable applications.
- Measure both infrared and visible light levels to enhance the control of LCD backlighting in mixed light source environments.
- Are an inexpensive yet effective means of adjusting backlighting to ease eyestrain and reduce power without distracting the end user.
