Wireless sensor networks based online ambient monitoring

Abstract

Indoor ambient monitoring plays a vital role in air quality management. Monitoring parameters include temperature, pressure, and humidity. The statistical data which is measured is sent using the existent wireless infrastructure which is based on the IEEE 802.15.4 b/g standards. The characteristics and performance of the resulted device are comparable with the ones that are provided by recognized solutions, like ZigBee-based sensor nodes. Further, gathered data can be implemented with data connectivity and ambient sensors As a result of testing, lifetime of the system is for up to three years on a single 3 V small battery.
