A low power wireless sensing system includes: a sensing device senses a peripheral environment to generate sensing data; a transmission device, coupled to the sensing device, is connected to an external network through a communication protocol to establish a wireless sensing network; a storage device stores the sensing data or first firmware; and a microprocessing device generates a control signal to control operations of the sensing device, transmission device and storage device according to the sensing data or a RF signal of the external network. The microprocessing device determines to read the first firmware according to the RF signal, so that second firmware built in the microprocessing device is updated and the control signal is adjusted correspondingly. The microprocessing device makes the transmission device enter a sleep state or perform reconnecting according to the RF signal. |
