Sensor Network Test-bed for Environmental Monitoring

Sensor networks consist of embedded devices deployed in different types of environments in order to sense its surroundings. Disaster management and rehabilitation is very important for all human beings. Environmental monitoring is the most important issue for everyday emergency situations and a significant driver for wireless sensor network research. Recent advances in electronics and communication technologies enable the devices to produce micro-sensors capable of performing a variety of different environmental applications. An implementation of a wireless sensor network test-bed is presented in this paper. This test-bed is a reactive network for environmental monitoring and evaluates the effectiveness of the network for data gathering using both laboratory and field tests. This sensor network test-bed monitors the environment: temperature and humidity in real-time. This paper deals with a test-bed that consists of a personal computer (PC) where an end-user can communicate with the sensor nodes through a base station (BS), which is implemented by combining HyBus kit (Hybus kit2420).
