Introduction• The architecture of wireless sensor

networks (WSN) consists of spatially distributed embedded devices, called sensor nodes, which form multi-hop mesh network and measure the parameters of interest within the application. These sensors are small, with limited processing and computing resources, and they are inexpensive compared to traditional sensors.

• Precision agriculture is a new modern solution in traditional agriculture. The monitored data is used to derive the most suitable decision which can help in control and adjustment of environmental parameters for obtaining better production yield.

• First monitoring parameters such as temperature, humidity and illumination, as these parameters are the main factors that influence the product yield and quality. The control and management decision is based on the analysis of the monitored data. Finally, automatic or manual control mechanism is implemented to complete the required environmental control and adjustment.

• Measurement parameters: temperature, humidity, pressure, light and acceleration.

• Measurement data obtained from the sensor nodes are wirelessly transmitted to a central base station for data collection. The base station makes a decision according to which the nodes perform appropriate task.

• Indoor measurements in Laboratory of Electrical measurement.
