The MetrySense-3000 is a modular wireless connectivity system that interfaces sensors and actuators with IP gateways and monitoring centers using a low-power wireless mesh network. It is designed to provide robust connectivity for remote monitoring over large geographical areas without external power or communication lines. The system uses IPv6/6Lowpan and RPL routing to allow for self-configuration, self-repair, and secure communication. Individual units can operate for 5 years on internal batteries or up to 20 years using small solar panels.
