1) The document describes WISENET, a wireless sensor network project that monitors temperature, humidity, and light in an office environment. It uses battery-powered sensor nodes called "motes" that form self-organizing networks to communicate data. 2) The design uses commercial off-the-shelf software like Apache, MySQL, and PHP. The client accesses data through a standard web browser. A server collects data from the wireless mote network via an application called WiseDB and stores it in a database. 3) The system block diagram shows how the client, server, and wireless mote network interact. The motes use TinyOS to efficiently sense data and communicate in an ad-hoc
