SenseDisc is a new concept of portable digital experimental
system with powerful function, which is available to the experimental teaching of primary and secondary schools all over the
world. Equipped with wireless & exquisite sensor modules, create
a simple and safe experimental environment for students, and
they can explore the science world as they wish.
SenseDisc is a multi-channel data logger, the entire�outward
appearance designs�succinctly�naturally and human friendly.
Every sensor modules are set around data logger flexibly, and has
its own independent connection port, not stereotypical. Each
series of SenseDisc data logger, has built-in accelerometer (3
Axis), GPS, ambient temp and barometer, more diversified and
high efficient.
SenseDisc adopts 3.5' TFT 480*320 touchscreen, and a built-in
1800mAh lithium battery (over 6 months of standby time). SenseDisc has two acquisition modes to choose from, stand-alone and
external equipment mode. When connect to an external equipment, can supports the Windows, Android, Mac OSX and iOS ope
ating systems, and provided wired mode and wireless linking
methods.

Connection of Sensor Modules
SenseDisc uses surround-type
design philosophies, namely the
sensor modules and the data
logger to form a circle-type
connection, 7 sensor modules can
be connected to the main body
simultaneously; Using pluggable
measuring modulus, and these
modulus can according the
requirements of experiment to be
combined freely.
When in usage, only need to insert
one module into any port of the
main body. Indicated as follows:

Stand-alone Mode
Before the first usage, please make
ensure the power is enough! In the
case of power shortage and power
unknown, please charging or connect
to power supply. When in charging,
1st, connect the USB cable to the
power adapter; 2nd, connect the USB
cable to the USB port of main body;
3rd, connect the power adapter to
power source.Or, connect the USB
cable to computer.
Power on: long press the power button
until the screen lit, and determines the
indicator light of sensor were lit (the
state of sensor communication can be
controlled via the built-in software:
when connecting to a sensor, the
indicator light is bright; Otherwise off).
Power off: long press the power button
until the screen turned off, and the
indicator light off.
