Signal-level Sensor Fusion Applied to Monitoring Environment Conditions

The use of sensors in environment monitoring and other applications is increasing every day. In order to improve the reliability and the integrity of the data acquired from the environments, the use of more than one sensor is frequent. The combination process of data or information provided from multiple sensors of the same nature and also of different nature is called sensor fusion. This paper describe an Internet based monitoring system that implements signal-level sensor fusion algorithms that increase the quality of the sensor data that can be used to make simple decisions. An analysis of known signal-level fusion algorithms of data of the same nature is also performed
