The SenStick2 platform are shown in Figure 1. SenStick2
is a platform including a hardware, 3D case data, software
and community, for making experiments of IoT easier. The
first key point is that all of necessary functions such as popular
8 sensors, BLE, battery and charging circuit are embedded
on to a ultra tiny board. Second key point is that will
share the data of 3D case design and all the users can print
their expected cases by themselves and attach our SenStick
to every things. Third key point is that sophisticated
mobile application can record both a ground truth video and
sensor data simultaneously.
