Si1145 UV / Ambient Light / Proximity Sensor
SEN-36002
-
SEN-36002 is a highly integrated carrier board designed for the Si1145 UV, Ambient Light and Proximity sensor IC from Silicon Labs. This sensor has 100mLUX resolution, and has a dynamic range of 1 LUX to 128 kLUX with IR correction. This means that whether your application is indoors in poor lighting conditions or outside in full sunlight, this sensor has you covered. In addition, we added a high power LED (150mA max, 20 degree) to take full advantage of the proximity sensing capability of this IC - something you won't see on most competitive carrier boards. Integration is easy with 4 x 4-40 sized mounting holes at the corners of the PCB and signal translation to handle interface voltages from 3V to 5V. The board is interfaced via an I2C interface and function pins have been broken out to a 0.1" pin header. The INT pin is also broken out for interrupt capability.
