Aiming at disadvantages of high test cost and greater mal-function probability of traditional wired sensors which need a large number of cables
a new kind of wireless sensor using modular design method based on MEMS technology is developed.The hardware integrated circuit five kinds of modules of wireless sensor which are signal detection module
micro-controller module
memory module
wireless transceiver module and power supply module are designed
and the software is implemented.The experimental system for this developed sensor is designed to study dynamic characteristic of sensor.The experimental results show that the developed sensor has such advantages as fast dynamic response
good linearity and repeatability
which is suitable for structural low frequency vibration measurement.
