1. A sensing platform, comprising:

  • a server;

    one or more remote sensing systems coupled to the central server, including;

    one or more local sensor(s) for target object monitoring;

    a wireless module coupled to a network through wireless a link; and

    a processor to read data from local sensor(s), and communicate information through the network using the wireless module, wherein the sensing system has a low power consumption mode where the processor puts the wireless module and the local sensor(s) in sleep mode or powered off, wherein the processor has a sleep or deep sleep mode, a power-off mode, and a wake up mode, wherein the local sensor(s) are accessed at a frequency 1/T1 and the wireless module is at lower frequency 1/Tw where Tw>

    T1, wherein the server receives monitored value from remote sensing systems and interacts with the remote sensing system;

    wherein the sensing system detects a second threshold Th2, that if a detected value is above Th2, the sensing system enters alarm state and sends alarm message to server; and

    wherein the sensing system exits alarm state to intermediate state when receives instruction from server.
