A New Wi-Fi based Platform for Wireless Sensor Data Collection

A custom designed WLAN (Wireless Local Area Network) based sensor interface ispresented in this paper. It is aimed at wirelessly interfacing a large varietyof sensors to supplement built-in sensors in smart phones and media players.The target application area is collection of human related motions andcondition to be applied in musical applications. The interface is based oncommercially available units and allows for up to nine sensors. The benefit ofusing WLAN based communication is high data rate with low latency. Ourexperiments show that the average transmission time is less than 2ms for asingle sensor. Further, it is operational for a whole day without batteryrecharging.
