Abstract: The disclosure is related to a sensor module, a sensor unit and a system for recognizing surrounding objects and defining an environment. The sensor module is installed in a sensor unit. The sensor module includes an optical element guiding the lights from the objects surrounding the sensor unit and to an image sensor, and the image sensor is used to sense the lights from the objects. The light can be directly from a light source inside the surrounding object or reflected by the object surface. The objects can be identified according to optical features obtained by the image sensor from surfaces of the objects. When the image sensor receives the two lights, guided by the optical element, and reads optical features being regarded as the unique IDs to identify the objects respectively. Therefore, an environment around the sensor unit can be defined.

Abstract: A portable electrical apparatus includes a sensor, a micro-controller, and a wireless positioning module. The sensor is configured for sensing a movement of the portable electrical apparatus to generate a sensing signal. The micro-controller is configured for receiving the sensing signal and comparing a threshold value with a sensing value corresponding to the sensing signal. The wireless positioning module is configured for positioning the portable electrical apparatus to generate a plurality of position data corresponding to a location of the portable electrical apparatus. When the sensing value is greater than the threshold value, the micro-controller loads the position data generated within a predetermined period, which is right after the sensing value being greater than the threshold value, compares the loaded position data with each other, and an alarm signal is sent out according to a comparison result.
