Introduction

ZigBit™ Amp is an ultra-compact, extended range, low-power, high-sensitivity 2.4GHz
IEEE 802.15.4/ZigBee
ware platform, this module is enhanced by an output power amplifier and an input low-noise amplifier,
and is designed for wireless sensing, monitoring & control and data acquisition applications. ZigBit Amp
modules eliminate the need for costly and time-consuming RF development, and shortens time to mar­ket for wireless applications with extended range requirements.

Two different versions of ZigBit 2.4 GHz Amplified modules are available: ATZB-A24-UFL with built-in
U.FL antenna connector and the ATZB-A24-U0 with unbalanced RF output. These modules are an addi­tion to the ZigBit family represented by ATZB-24-A2 and ATZB-24-B0. In addition Atmel offer the ZigBit
900 MHz Wireless Module ATZB-900-B0 [2].

1.2 Applications

ZigBit module is compatible with robust IEEE 802.15.4/ZigBee stack that supports a self-healing, self­organizing 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 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)
