[Tinyos-help] A Scenario to study TinyOS and WSN

[sunchao]

Hello Every body:
    I'm a college student in China and my research interest is Wireless 
Sensor Network. Currently I'm not very familiar with TinyOS and other 
WSN applications, and I want to learn them by practice - our lab have 
about 30 Micaz motes and related facilities. Can some one introduce me 
some very simple application scenarios that we can deploy using these 
motes, so that we not merely use these motes doing just some very simple 
tutorial tests.

Chris
