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 for free at any
time using the provided firmware update.
The Edu-Logger current sensor houses a shunt resistor
and an amplifier. The circuit's current passes through
the shunt resistor and its electric potential is measured
using a very fast, high input impedance differential
operational amplifier with protected inputs. Using
ohm’s law (I = V/R) the current is calculated from the
known resistance and voltage values.
The shunt resistor is very high power (to protect it in
high current) and very small resistance (in order not to
affect the circuit conditions). The protection is up to 5
A.
