Introduction
Summary
ZigBit
®
is an ultra-compact, low-power, high-sensitivity 2.4GHz IEEE 802.15.4/ZigBee
®
OEM module based on the
innovative mixed-signal hardware platform from Atmel. It is designed for wireless sensing, control and data acquisition
applications. ZigBit modules eliminate the need for costly and time-consuming RF development, and shorten time-to-
market for a wide range of wireless applications.
Two different versions of 2.4GHz ZigBit modules are available: the Atmel ATZB-24-B0 module with balanced RF port for
applications where the benefits of PCB or external antenna can be utilized and the Atmel ATZB-24-A2 module with dual
chip antenna satisfying the needs of applications that require integrated, small-footprint antenna design.
1.2
Applications
ZigBit module is compatible with robust IEEE 802.15.4/ZigBee stack that supports a self-healing, self-organizing mesh
network, while optimizing network traffic and minimizing power consumption. Atmel offers two stack configurations:
BitCloud and SerialNet. BitCloud is a ZigBee PRO certified software development platform supporting reliable, scalable,
and secure wireless applications running on the Atmel ZigBit modules. SerialNet allows programming of the module via
serial AT-command interface.
The applications include, but are not limited to:
•
Building automation and monitoring
•
•
•
Lighting controls
Wireless smoke and CO-detectors
Structural integrity monitoring
•
•
•
•
•
•
HVAC monitoring and control
Inventory management
Environmental monitoring
Security
Water metering
Industrial monitoring
•
•
Machinery condition and performance monitoring
Monitoring of plant system parameters such as temperature, pressure, flow, tank level, humidity,
vibration, etc.
•
Automated Meter Reading (AMR)
