This research studies the estimation of the number of walking humans by using footsteps measured by the sensor network. We develop a new wireless communication module mounted the omni directional microphone. This module is able to digitally record the sound for about 16 seconds at the sampling frequency 8 kHz and communicate each module at 160Kbit per second. Using the sensor network constructed from these modules, and we measure the footstep of walking human. From the sensing data, we are able to estimate the number of walking humans around a module, walking pattern and walking direction. Furthermore the result implies the capability to estimate the motion of individual walking human by combining each node's data.
