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 pulse sensor's probe consists of a fingertip/earlobe
clip which houses an infrared light source and an
infrared light detector on opposite sides.
The blood in the finger flows forward (oxygenated) and
backward (deoxygenated with CO
). The IR light

absorbed by the deoxygenated blood and the detected
light intensity changes are according to the heart pulses.
