Embodiment 1

[0025] Such as figure 1 as shown,

[0026] A multi-sensory sensor applied to the Internet of Things, the sensor includes: a sensor housing, a multi-sensory sensor part and a sensor power supply part; the multi-sensory sensor part and the sensor power supply part are all arranged in the sensor housing; the sensor The energy supply part is used to supply energy to the multi-sensory sensor part; the multi-sensory sensor part includes: a passive sensor part and an active sensor part; the passive sensor part passively perceives changes in environmental parameters and obtains the results of parameter changes; the The active sensor part includes: a transmitting part, a receiving part and an analyzing part; the transmitting part comprises a first transmitting part and a second transmitting part, and both the first transmitting part and the second transmitting part emit sound, light and / or electric waves Finally, the receiving part receives the reflected wave and the direct wave; the ...

Embodiment 2

[0029] On the basis of the previous embodiment, the process of performing direct wave filtering by the passive sensor part performs the following steps: use the following formula to calculate the direct wave and the second direct wave of the first transmitting part received by the receiving part through Fourier transform Delay between direct waves of the transmit part: Among them, r 1 (t) is the direct wave of the first transmitting part, F[r 1 (t) is its corresponding Fourier transform; r 2 (t) is the direct wave of the second emission part, F * [r 2 (t)] is the conjugate of its corresponding Fourier transform; f is F[r 1 (t) and F * [r 2 (t)] corresponding frequency, x is the unknown quantity of Fourier transform; Then calculate the cross-correlation coefficient between the direct wave of the first emission part and the direct wave of the second emission part: in, means r 2 (t) inverse Fourier transform; Amplified by 2c times, the reflected wave after fil...

Embodiment 3

[0033] On the basis of the previous embodiment, the functional part of the sensor includes a transformer; the transformer is elastically connected to a magnet through a spring; a metal coil is arranged around the outside of the magnet; The sensor part is connected.
