Technical background
The philosophy behind NeuLog's plug and play
technology is based on each sensor's ability to store its
own data due to an internal flash memory chip and
micro-controller in each plastic NeuLog body. This
technology allows the sensor to collect and then store
the digital data in the correct scientific units (for
o
o
example:
C,
F, Lux, %, ppm).
The sensor is pre-calibrated at the factory. The built-in
software in the logger can be upgraded for free at any
time using the provided firmware update.
The UVA sensor uses a special photodiode which reacts
with electromagnetic radiation in the UV spectrum. An
internal selective filter limits the range down to
specifically the UVA range (315 to 400 nm) so only the
UVA rays may pass through.
UVA rays which strike the photodiode release free
electrons which generate a voltage that can be
measured easily and accurately.
Voltage is converted into UVA density easily because it is
directly proportional to the known surface area which is
being measured.
