1.1 Summary
Section 1
Introduction
ZigBit™ 900 is an ultra-compact, exte nded range, low-power, high-sens itivity 784/868/915 MHz
IEEE 802.15.4/ZigBee
It is designed for wireless sensing, control and data acquisition applications. ZigBit modules eliminate
the need for costly and ti me-consum ing RF dev elopment, and sho rtens time t o market for a wide ran ge
of wireless applications.
This module is the latest addition to the ZigBit family also represented by 2.4 GHz modules ATZB- 24A2/B0 [1], and ATZB-A24-UFL/U0 [3].
1.2 Applications
ZigBit 900 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 r eliab le, s calab le, a nd secure wireless applications running on Atmel’s
ZigBit modules. SerialNet allows programming of the module via serial AT-command interface.
The applications include, but are not limited to:
•
Building automation & monitoring
– Lighting controls
– Wireless smoke and CO detectors
– Structural integrity monitoring
• HVAC monitoring & 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)
®
OEM module, based on the innovative Atmel’s mixed-signal hardware platform.
