Project Context
This system aims:
•to connect wireless sensors measuring environmental data linked to
drought indicators (temperature and humidity of soil and air,
pluviometry, etc...).
•to install a spatio-temporal database communicating with a Web
mapping application for a monitoring in real time.
The main idea of this project is to implement an intelligent system to
help low incomes farmers to face drought impacts.

This new technique allows to study the temporal evolution of the environment
parameters from which we can extract the drought phenomenon indicators.
Spatio-temporal conceptual models seek to answer the users who need to
manage soil water content for irrigating, fertilizing or other activities for
pursuing crop yield augmentation.
The study will be applied in Siliana watershed Northern Tunisia.

Conclusion
In this project we implemented an intelligent system using wireless sensors
network to help low incomes farmers to face drought impacts.
a spatio-temporal database communicating with a Web mapping application
for monitoring, in real time, environmental data linked to drought indicators
This tools help, for example, to answer the users who need to manage soil
water content for irrigating, fertilizing or other activities for pursuing crop
yield augmentation.
This system will be installed in Siliana watershed Northern Tunisia
