1. Introduction
ST940: Personal / Asset Tracking Device
The ST940 is a waterproof (IP65 compliant) hard-cased ultra-mini tracking device for various usages such as asset
tracker and personal trackers.
Without any efforts for connecting wires, the ST940 works autonomously with its built-in battery. If users want to track
an object with the ST940, all they have to do is just simply put it into the box or the carry bag where the object is
contained. And then, users can track the locations of such an object and receive an alert if the object enters or leaves
a pre-defined zone.
This non-wiring device is so small that it can be hidden after being placed. So, the waterproof ST940 is suitable for
covert tracking even in rainy weather conditions. The ST940 is ideal for tracking various objects such as people,
vehicles (especially small vehicles or motorcycles), boats and valuable fixed/moving assets like expensive
merchandises, computers, smart phones, electronic products, machinery and so on.
In addition to 3-axis acceleration sensor, the ST940 has various functionalities such as low-power consumption
