PROBLEM TO BE SOLVED: To provide a wireless sensing device with a vibration sensor which is constituted to detect mechanical vibration and to generate an electric signal in response to the mechanical ***: A device is provided with a transceiver suitable for establishing wireless connection between a wireless sensing device and a remote device. The transceiver is constituted to receive at least a part of an electric signal from a vibration sensor, to be switched to on according to intensity of the part of the electric signal, and to transmit a radio signal to the remote device. The radio signal is suitable for triggering a resultant action in the remote *** DRAWING: Figure 1
