WIRELESS SENSOR NODE FOR DATA COLLECTION IN RESTRICTED ZONE

Abstract

The wireless sensor networks combine sensing, computation and communication into a single tiny device. The application of wireless sensor network technology is to monitor remote environments, collect data from particular area. The wireless sensor network architecture includes hardware platform which contain metallic skeleton with attached solar panels .This mainly contains temperature sensor, humidity sensor, smoke detector, sound detector, PIR etc The main contributions of this work are (1) a general architecture that meets efficiency and flexibility requirements of wireless sensor networks, (2) an implementation of the architecture using current microcontroller and wireless transmitter. The environmental data collection application is characterized by nodes continually sensing and transmitting data back to a set of base stations that store the data. These networks generally require very low data rates and extremely long lifetimes.
