Environment sensing device and environment sensing system

The invention discloses an environment sensing device and an environment sensing system. The device comprises a spherical shell, and a central control device, a camera device, an ultrasonic device and a wireless communication module, which are arranged in the spherical shell. The ultrasonic device is used for performing ultrasonic localization according to a control instruction of the central control device to obtain ultrasonic localization data. The camera device is used for shooting image according to the control instruction of the central control device. The wireless communication module is used for transmitted the ultrasonic localization data and the image data obtained by the camera device to a sensing control terminal according to the control instruction of the central control device. The device and the system of the embodiment of the invention could be used for sensing the environment well, especially sensing the environment of narrow and small space.
