Technical background:
The philosophy behind Edu-Logger’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 Edu-Logger body.
This technology allows the sensor to collect and then
store the digital data in the correct scientific units (
o
C,
o
F, Lux, %, ppm, for example).
The sensor is pre-calibrated at the factory. The built-in
software in the logger can be upgraded at any time
using software.
Inside of the Edu-Logger spirometer sensor’s metal
tube attachment there is a funnel which creates a
difference of the air pressures before and after the
funneling piece according to the airflow speed. A
pressure differential sensor is connected to both sides
of the funneling piece.
The sensor controller calculates accurately the air flow
speed according to this pressure difference.
Using the Edu-Logger software, you can easily
determine the area under the curve to calculate total
lung capacity.
