Scheme-it
Introduction
Schematic Drawings
Use schematic symbols to layout the components of your circuit and make electrical connections. With symbols ranging from amplifiers to vacuum tubes, as well as the ability to build custom symbols, you are able to design nearly any circuit. Access to Digi-Key's extensive part database also allows you to browse and assign orderable part numbers.
Diagram Building
Use the system blocks to refine your idea at a conceptual level. The higher-level components are there to help you plan out the broader intentions of your idea. This powerful block chain library allows you to quickly layout the function of circuit. Once your design is ready, save and share with your colleagues.
Flow Chart Creation
The flow chart creation option will help transition your concept to a design. Use the library of arrows, shapes, UML symbols, and more to sort out the flow and annotate each stage. Insert a textbox, math function/formula, image, or link to help illustrate the objectives and make your plan easy to follow.

The design uses ATZB-RF-212B-0-U Zigbit 900MHz wireless module that provide the zigbee communication protocol between the host system and I/O components. The AT89C2051-24PU 8-bit MCU manages the I/O components with the commands uploaded into it. It uses relay driver that supports the low voltage relay for switching the lamp. The system have proximity and temperature sensors that detects human presence and some related objects that need to be considered. The speaker can be used for alarm or delivering a simple signal or message. In the power supply side, it uses two Low DropOut (LDO) regulator to provide 3.3V and 5V while a 12V supply is also provided after diode bridge. The design can be used in energy saving system of commercial and residential applications. It can be used in industrial application but requires some modifications so that it will fit to the system.
