Aiming at problems of many disadvantages of traditional wire test

for example

hard to install

the wire is too complex

and there are many interferers

which will cause the large noise and distortion of signal

sometimes even cause invalidation of collected signals

a wireless sensor networks（WSNs）based on multi-ranged accelerometer is proposed and its capabilities are tested.Test results show that the designed WSNs can transmit output signal of multi-ranged accelerometer without loss

thus achieve measurement of acceleration signal in covering region.
