Helpout Sri Lankan Farmers via sensor Networks



1 Abstract.
The objective of this survey is to ¯nd out, how can help out Sri Lankan
farmers, by using sensor networks. It can be used environment-related infor-
mation for the improvement of farming strategies. Choice of crop varieties,
sowing and harvest periods, prevention of pests and diseases, efficient use of
irrigation water etc. is depends on that environment-related information.

2 Introduction.
The majority of people in Sri Lanka carry their lives by doing farming. Farm-
ing in Sri Lanka is highly depends on the amount of rain fall. Therefore the
crop yields are highly unreliable due to the variability in both rainfall amount
and its distribution. Information on the temporal and spatial variability of
environmental parameters, the impact on soil, crop, pests, diseases and other
components of farming play a major role in formulating the farmers' strategy.

Today, large mechanized farms in developed countries use advanced tech-
nologies, including in-field sensors, geographic information system (GIS), re-
mote sensing, crop simulation models, prediction of climate and advanced
information processing and telecommunications. Similar information can be
highly useful to farmers in developing countries like Sri Lanka. However, the
techniques that used by developed countries like above are difficult to apply
to Sri Lanka that have small land holdings.This survey is going to look at
how can improve productivity of agriculture in Sri Lanka by using wireless
sensor network technology for environment monitoring.
Real-time data collection in rural area and farms is need for management
of agricultural production. Air-temperature, humidity, solar-radiation inten-
sity, soil temperature, soil moisture, CO2 concentration, UV, IR, leaf-wetness
and soil moisture are some directly caused factors for agriculture.Can it uses
Sensor networks for sense that factors and can it gives a better solution to
the farmers using that sense data? The purpose of this report is to find out
an answer for this question....
