1. A sensing device comprising:

  • at least one central processing unit (CPU);

    at least one storage unit coupled to the CPU configured to store the sensing device'"'"'s sensing function and supported network types;

    a sensor coupled to the CPU;

    a communication device controlled by the CPU; and

    a grouping system stored in the storage unit, the grouping system comprising a plurality of modules executable by the CPU to cause the CPU to;

    inquire the sensing device'"'"'s sensing function, supported network types stored in the storage;

    interact with one or more sensing devices in networks of the supported network types, share the sensing function with the one or more sensing devices, and acquire the one or more sensing devices'"'"' sensing functions;

    form a function group by grouping the sensing device with at least one of the one or more sensing devices that have the same sensing function as the sensing device'"'"'s sensing function based on a pre-defined first rule and through interaction with the one or more sensing devices, and exchange first configuration parameters of the sensing device with other sensing devices within the function group;

    designate one of the sensing devices of the function group as a master sensing device, and the rest of the group as slave sensing device(s), based on the exchanged first configuration parameters and a pre-defined second rule; and

    control the communication device to receive operation parameters and commands from a device outside the function group and relay the operation parameters and commands to the rest of the function group, upon a condition that the sensing device is the master sensing device;

    wherein the pre-defined first rule comprises;

    when the sensing devices having the same sensing function are distributed in two or more networks of the supported types, choosing those in a network with lower energy consumption, shorter distance and better network route to form the function group.
