In order to achieve long-term unattended vibration measurement and target recognition

design an ultra low-power consumption wireless vibration sensor. The sensor adopts electromagnetic sensitive element to obtain vibration signal

and completes target recognition and data transmission through software and hardware design of signal conditioning

data acquisition

data analysis

data storage and wireless communication. Realize ultra-low power consumption working through free power supply sensor and dual processor design

and use WSNs monitoring mode to build wireless

distributed vibration monitoring network. Test results show that the sensor can complete vibration signal measurement and target recognition of caterpillar vehicles and pedestrians

its current is only30 μA

expected to work continuously for more than 200 days.
