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.
In spite of that, the probe needs to be offset prior to
initial use. Please review the “Sensor offset” guide at
the beginning of this document for detailed
instructions.
The CO
2
sensing element consists of a cation
(Na
+
) solid electrolyte formed between two
electrodes together with a printed heater (RuO
2
)
substrate.
The cathode (sensing element) consists of lithium
carbonate and gold, while the anode (counter
electrode) is made of gold.
