Introduction
2.1
OPT3001
The OPT3001 is an ideal sensing device for measuring ambient light. Mea-
surements can be made from 0.01 lux up to 83k lux without selecting full-scale
ranges by using the built-in, full-scale setting feature. This capability allows
light measurement over a 23-bit effective dynamic range.
The spectral response of the ambient light sensor is tightly matched to the
photopic response of the human eye and has significant infrared rejection. This
tightly matched response offers accurate lux readings of different spectral sources,
even under dark glass.
The digital operation is flexible for system integration. Measurements can
be either continuous or single-shot. The control and interrupt system features
autonomous operation, allowing the processor to sleep while the sensor searches
for appropriate wake-up events.
The low power consumption and low power-supply voltage capability make
this device ideal for battery-powered applications.
2.2
Beagle Bone Black
Beagle Bone Black is an
Open Source Hardware
Software Development Plat-
form using Texas Instruments’ AM335x System-on-Chip device.
It provides an easy to use Software Development Platform based on an ARM
Cortex-A8 CPU together with many other peripherals integrated into the die.
2.3
Linux Kernel
The
Linux Kernel
was created by Linus Torvalds back in 1991. It’s a General
Purpose Operating System which works in many different architectures includ-
ing, but not limited to, x86, ARM, ARC, Power, MIPS, and Alpha.
