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.
