Seismic sensors in wireless sensor networks (WSNs) find
increasing applications ranging from disturbance detection
to critical compound security. Analog design of these sensor
boards plays critical role in system performance as geophone
sensors generate signal in microvolt’s range.When geophone
signal is amplified, filtered, and digitized, the data are usually
transferred in WSN to a central processing unit. Although
the design of wireless nodes has been matured to great
extent such that there exist many integrated circuits (ICs) for
transceivers, there is little known about the electronic design
of the seismic sensor board.This study aims to bridge this gap
by analyzing the sensor board requirements and electronic
design steps.The design of a wireless node is also presented to
fulfill low power requirements but not detailed as this design
is relatively straightforward.
