About SmartMesh WirelessHART
Dust Networks’ SmartMesh
®
WirelessHART is an industry-leading wireless networking solution designed for critical monitoring and
control applications. WirelessHART serves a wide range of applications from renewable energy generation, such as solar and wind power,
to factory machine health monitoring and data center HVAC energy management. The SmartMesh WirelessHART system delivers
dynamic network optimization and intelligent routing to achieve unsurpassed levels of wireless network scalability, system-wide reliability
and low latency, coupled with industrial-class security. Additionally, ultra-low power operation permits even greater deployment flexibility
for wire-free applications.
Product Description—LTP5900
The LTP5900 mote module combines Dust Networks’ robust sensor networking solution breakthrough Eterna
TM
SoC technology in an
easy-to-integrate 22-pin module. As part of the SmartMesh WirelessHART system, the LTP5900 enables customers to integrate a
standards-based wireless network into sensors and actuators to provide scalable bidirectional communications.
The LTP5900 is designed for use in line-powered, battery-powered, or energy-scavenging sensor and actuator applications that demand
reliable performance and ultra-low power operation. With Dust Networks’ innovative IEEE 802.15.4-compliant design and integrated
power amplifier, the LTP5900 enables a decade of battery life on two AA batteries. All motes function as wireless routers, enabling a
redundant, high performance, full-mesh topology.
The LTP5900 integrates all radio circuitry components, including an MMCX-type antenna connector to eliminate the need for complex RF
design. To accelerate customer development time and reduce development costs, Dust Networks provides a fully engineered RF solution,
comprehensive APIs, and complete development documentation.
