Sensor Integration in a Wireless Sensor Network System for Environmental Monitoring System

This paper presents the implementation of the event-driven
Wireless Sensor Network (WSN), which is used for
environmental monitoring using soil moisture sensors. The
problem faced is that the current Wireless Soil Sensor
Networks are not reactive to the weather conditions around
it. Which means it takes reading samples at constant rate
throughout its operation. So, the aim is to design a system
that takes soil samples only when it is triggered by an
outside event, which in this case study involves the event of
rain. The objective of this paper is to develop a wireless
sensor network by modifying the programs that run the
sensor networks and interfacing the motes with external
sensor. The wireless sensor network system that was
developed has variable sampling rates with interfaces to Soil
Sensors and Rain Gauge. The developed system would
provide an applicable system that can be used in the
agriculture industry for monitoring large estates, landslide
detection and flood warning systems.
