Wireless Mesh Network Time Server
The solar-powered Wireless Mesh Network Time Server receives time and date data from a GPS receiver module and rebroadcasts it into a mesh network through an XBee module for use by any devices attached to the network. An NiCd battery pack powers the server and a small PV panel recharges it. In Normal mode, the server broadcasts the time and date once per minute. If another device on the network requests it, the server switches to Stream mode increasing the transmission speed to once per second. The battery pack’s voltage is measured and transmitted in Test mode. The relatively simple software enables you to program in a high-level language (MPIDE) while focusing on time and energy conservation.
