Abstract: In this paper we present a prototype of sound pressure level (SPL) node, built out of discrete off-the-shelf components (COTS). This is a preliminary step in a more ambitious project where an ultra low power SPL will be integrated in a chip. This first prototype was built using low-power and the final current consumption resulted less than 300 A. The wireless link was implemented using a 900Mhz MICA2 mote from Crossbow?. The prototype was used to demonstrate the feasibility of low-power sensor networks for urban acoustic pollution monitoring. An experiment is reported where the noise level of the city of Bahia Blanca was monitored during one weekend, using a 900Mhz MICA2 mote from Crossbow?. The prototype was used to demonstrate the feasibility of low-power sensor networks for urban acoustic pollution monitoring. An experiment is reported, where the noise level of the city of Bahia Blanca was monitored during one weekend, off-the-shelf components (COTS).
