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

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