Recent development and future perspective [1] of Wireless Sensors in agriculture and food industry is done. The technology details besides cost effective solutions and how WSN have been used in P A to assist in spatial data collection, precision irrigation and supplying data to farmers are all mentioned.
Advantages of airborne remote sensing for identifying and mapping weeds in crops in P A have been greatly accepted worldwide [2], [3]. Sensing and data acquisition along with mapping is done within hours.
Feasibility study on GSM-SMS technology application to field data acquisition done [4].
Use of Wireless Sensor Networks (WSNs) results in lowcost and low-power consumption deployments, therefore becoming a dominant option. It is also well-known that crops are also negatively affected by intruders (human or animals) and by insufficient control of the production process. Videosurveillance is a solution to detect and identify intruders as well as to better take care of the production process [5].
WSN technologies enabled monitoring and control of greenhouse parameter in precision agriculture, especially control of equal distribution of water to all crops in the whole farm or as per the requirement of the crop. Green house technology may be the best solution [6].
The basic objectives of site-specific management of agricultural inputs are to increase profitability of crop production, improve product quality, and protect the environment. Information about the variability of different soil attributes within a field is essential for the decision-making process. The inability to obtain soil characteristics rapidly and inexpensively remains one of the biggest limitations of precision agriculture [11].
