  Precision agriculture has been considered as a new technique to improve
agricultural production and support sustainable development by preserving
planet resource and minimizing pollution. By monitoring different parameters of
interest in a cultivated field, wireless sensor network (WSN) enables real-time
decision making with regard to issues such as management of water resources for
irrigation, choosing the optimum point for harvesting, estimating fertilizer
requirements and predicting crop yield more accurately. In spite the tremendous
advanced of scalar WSN in recent year, scalar WSN cannot meet all the
requirements of ubiquitous intelligent environmental event detections because
scalar data such as temperature, soil humidity, air humidity and light
intensity are not rich enough to detect all the environmental events such as
plant diseases and present of insects. Thus to fulfill those requirements
multimedia data is needed. In this paper we present a robust multi-support and
modular Wireless Multimedia Sensor Network (WMSN) platform, which is a type of
wireless sensor network equipped with a low cost CCD camera. This WMSN platform
may be used for diverse environmental event detections such as the presence of
plant diseases and insects in precision agriculture applications.
