GE Yang1, LI Jian-qing1, CHEN Fei1, et al. Design of sensor module for WSNs target detection[J]. 2009, 28(9): 94-96. DOI: 10.13873/j.1000-97872009.09.033.
A sensor module for wireless sensor networks(WSNs) target detection is introduced.Its hardware and software design and algorithm are described.This design is mainly composed of sensor unit
microprocessor unit and RF communications unit.The vibration
sound and temperature sensors signal of external target are collected in the sensor unit.In the microprocessor unit
the data is pretreated in DSP and the signal feature is obtained.In RF communications unit
the value of the signal feature is transferred to PC through WSNs.Experiments show that this design has a good stability and reproducibility
and can be used in a variety of environments to detect targets.
