Milpitas, CA ? Cermetek Microelectronics, Inc. today announced the
CH4390 modular radio for wireless sensor networks. The CH4390 simplifies
wireless sensor network design and operation. Any CH4390 module can serve as
network coordinator, remote sensor node, or repeater node. At the remote sensor
node all sensors and actuators connect directly to the CH4390. Applications for the CH4390 include process
controls, infrastructure monitoring, and environmental monitoring.
The CH4390 is a 900 MHz, frequency hopping, spread
spectrum, transceiver. It uses a proprietary scheme, developed in cooperation
with Sandia National Laboratories, specifically for remote sensor networking. The CH4390 is optimized for rapid
synchronization, extended battery life, and maximum range. The CH4390 has
earned FCC Part 15 modular approval.
The Cermetek patented SensorOnAir feature simplifies
operation of the sensor network.
SensorOnAir allows the sensors connected to a remote CH4390 to be read
and actuators controlled with simple serial commands to the network
coordinator. The remote sensor node needs no added intelligence. Each CH4390 supports up to five, twelve-bit
analog inputs and twelve programmable digital inputs/outputs.
With its simplified networking the CH4390 radio
module enables a wide variety of applications.
Highway departments can monitor the stresses on bridges on key
transportation routes. Food processing
plants can watch every stage of the process from raw material input to
completed product. Nuclear and chemical
plants could use the CH4390 in a perimeter monitoring system to detect and
track the occurrence of any leaks or emissions.
?With the CH4390 we focused on simplifying the
process of building and operating the wireless sensor network,? stated Cermetek
Marketing Manager, Steve Clary. ?The
simplified implementation permits system developers to easily incorporate
wireless remote sensor networks.?
