A wireless sensing system includes a sensing device, a transmission device, and a micro-processing device. The sensing device senses a physical quantity or a chemical quantity of peripheral environment and generates a sensing signal. The transmission device coupled to the sensing device performs data transmission with an external network through a radio-frequency signal. The micro-processing device generates a corresponding operation according to the sensing signal or the radio-frequency signal. After the system is initialized, the micro-processing device and the transmission device are in a sleep state. When the sensing signal is larger than a threshold value, the sensing device wakes the micro-processing device and the transmission device up.
