U-Bee T28 IEEE 802.15.4 wireless digital multi-function modules UPSC 
U-Bee-T28 is a plug and play modules for Zigbee wireless digital 
Containing an embedded solution. No set up PC, without development environment, do not need to have the programming, users can easily complete a variety of applications. Greatly simplify the development process and human resources. 
Powerful advantages: no need to research and development, quality and cheap, digital products, replacement upgrades.   

(Free writing programs), (free development environment), (avoid creating risk), (maintenance-free cost), (free of human overhead) 

To save time, reduce costs and risks 

Applications: CCTV security monitoring, lighting engineering, fire engineering, access control engineering, air-conditioning engineering, environmental engineering 
Intelligent home, intelligent buildings: lighting, wireless switches, wireless remote control, remote control and management

U-Bee-DK Development Kit UPSC wireless modules 

To simplify the complexity of the developer's work and work schedule, easy to carry U800C together to provide the digital board, the US-T28 to do an integrated wireless transceiver modules to facilitate application development for developers. 
U-800C bearing plate with a multi-functional design, choose to use RS232 / or RS485 serial communication, or the analog / digital interface. 
U800C and U-Bee T28 development tools, with multiple modes of operation. (Through a simple plug PIN) 
Data Transfer = RS 232 / RS 485 
Digital Interface = a) a single point on the single-point b) single-point-c) Multi-multipoint 
Analog Interface = a) a single point on the single-point b) single-point-c) Multi-multipoint 
Hybrid analog / digital interface = a) a single point on the single-point b) single-point-c) Multi-multipoint
