Description
SmartMesh WirelessHART wireless sensor networks are
self managing, low power networks built from wireless
nodes called motes. The LTP™5901-WHM/LTP5902-WHM
is the WirelessHART mote product in the Eterna®* family
of IEEE 802.15.4 printed circuit board assembly solutions,
featuring a highly-integrated, low power radio design by
Dust Networks® as well as an ARM Cortex-M3 32-bit
microprocessor running Dust’s embedded SmartMesh
WirelessHART networking software. Both the LTP5901-
WHM (with chip antenna), at 24mm × 42mm, and the
LTP5902-WHM(withMMCXconnector),at24mm× 37mm,
are designed for surface mount assembly.
With Dust’s time-synchronizedWirelessHARTnetworks, all
motes in the network may route, source or terminate data,
while providing many years of battery powered operation.
The SmartMesh WirelessHART software provided with
the LTP5901/2-WHM is fully tested and validated, and is
readily configured via a software Application Programming
Interface (API).
SmartMesh WirelessHART motes deliver a highly flexible
network with proven reliability and low power performance
in an easy-to-integrate platform.
