Design and implementing system to study environmental noise pollution using microcontroller

Abstract

This paper proposed a system and presents it’s result obtained in a study on environmental noise pollution in the city of Baghdad, Iraq. The sensing system is built on Atmega128 and CC2420 platform. We designed and implemented a sensor function for wireless sensor network application using special network named (WSN) for measuring environmental acoustic noise. Based on the readings obtained became clear that 90 % out of the locations during the peak time have equivalent sound level over 75 dBA, and 60 % out of the total number of locations measured display during the normal time equivalent sound level over 75 dBA.
