Wireless Mesh Nodes are application-specific battery-powered devices with sensors, I/Os, microprocessors, onboard data storage, and wireless networking capabilities.
Advanced energy management options enable multi-year battery-powered operation in environments without grid power.
Product highlights
- Simple, quick and reliable installation in harsh environments without grid power outlets
- Battery pack options for battery life up to 10+ years
- All nodes have a unique 32-bt identification number (RFID) enabling resource and asset location and tracking
- Mobile nodes quickly attach themsleves to the nearest fixed node enabling tracking of mobile assets or personnel and text messaging
- Standard industrial I/Os, regulated power output options and a remotely configurable embedded application allow plug and play monitoring of sensors and control of actuators
- Hundreds of nodes can share one or more Newtrax Gateway
- Anywhere, anytime, from any web-enabled device, users can remotely configure, monitor and control the nodes via the Central Server
