             abstract = "A Wireless Sensor Network is presented in this paper. It is 
                         designed for monitoring Temperature, Relative Humidity and 
                         Atmospheric Pressure. The network contains four sensor nodes which 
                         perform measurements and transmit them through a ZigBeeŽ Network 
                         and a coordinator node which gathers all measurement data, stores 
                         them into a Flash Card and provides them through a HTML page 
                         accessed through an IP address. The coordinator also checks the 
                         signal transmission power from each sensor and registers it. It 
                         also has a real-time clock to stamp all measurements with the 
                         actual date it comes from the sensor nodes. The data from each 
                         sensor node are stored through a file in a SD/MMC card. The 
                         network uses 32-bit microcontrollers to enhance data processing 
                         and interface with peripherals, such as sensors with digital 
                         output. The sensor nodes use a Temperature and Humidity sensor 
                         from Sensirion and a Barometric Pressure sensor from Freecale. The 
                         microcontroller (especially for the node) also performs a deep 
                         power management to save energy from the battery. Tests performed 
                         with a prototype version in a instrumented tower in the Amazon 
                         rainforest, with an atmospheric balloon and autonomy tests for the 
                         sensor nodes demonstrate the network can be applied to 
                         Environmental Monitoring at a low cost deployment.",
