    2.Summary

    REX3SP is an ultra-compact, low-power, high-sensitivity 2.4GHz IEEE 802.15.4/ZigBee module based on the innovative Rexense's hardware platform. It is designed for wireless sensing, control and data acquisition applications. RexBee modules eliminate the need for costly and time-consuming RF development, and shorten time to market for a wide range of wireless applications.

     

    3.Applications

    RexBee module is compatible with robust IEEE 802.15.4/ZigBee stack that supports a self-healing, self-organizing mesh network, while optimizing networ traffic and minimizing power consumption. Rexense offers two stack configuations: Custom and Transparent ( currently supports STM32W RexBee module only ). Custom software supports reliable, scalable, and secure wireless applications running on RexBee modules. Transparent software allows programming of the modile 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

    ■ HV/AC monitoring & control

    ■ Inventory management

    ■ Environmental monitrring

    ■ 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)

     

    4.Advantages

    ■ Small physical footprint and low profile for optimum fit in even the smallest of devices

    ■ Best-in-class RF link range

    ■ Extended battery life

    ■ 4 PCB board, good ESD/EMC protection ablilty

    ■ Ample memory for user software application

    ■ Mesh networking capability

    ■ Easy-to-use low cost Evaluation Kit

    ■ ISM Worldwide license-free operation 

    ■ FCC certified : FCC ID : O46RY12M02
