4. Wireless sensor network
 definition
A wireless sensor network (WSN) consists of spatially
distributed autonomous sensors to monitor physical or
environmental conditions, such
as temperature, sound, pressure, etc. and to cooperatively
pass their data through the network to a main location.

5. Wireless sensor network
 Advantage of WSN:
•Provide a bridge between the real physical and virtual
worlds.
•Allow the ability to observe the previously unobservable at a
fine resolution over large spatiotemporal scales.
•Have a wide range of potential applications to industry
science, transportation, civil infrastructure and security.

1.Sensorsnodes:
where each node is connected to one sensors which are composed
of a radio transceiver with an internal antenna or connection to an
external antenna, a microcontroller an electronic circuit for
interfacing with the sensors and an energy source, usually
a battery or an embedded form of energy harvesting

8. This node processes and translates all the information sent by the
sensor nodes to make it compatible with the application running
on user’s computer.

12. Introduction
Wireless sensors networks and environmental care have
been always very close to each other, either because they
have been evolving alongside one another during the last
decade or because WSN features seem to suit very well
into the environmental evaluation requirements and When
talking about environmental applications for WSNs

A-Agricultural Monitoring:
Agricultural monitoring always focuses mostly on
farming area.
it is important to have a monitoring system to monitor
animal behavior and produce a report regarding their
health or behavior in real-time system

B- Agricultural Monitoring:

16. This is an effort to control and monitor the climate
change, develop a monitoring system that manages and
keeps data in real time and focuses on the processing of
spatiotemporal query
