The objective of this project is to develop a simple and inexpensive home automation network with discrete elements, available to any person without specialized knowledge, to automate from a house to a building complex, which functions independently and provide alternative free energy, with light the whole house with LED diodes.  Features of the microHomeLan network for home automation- Network based on RS-485 standard.
- Communication 8-bit asynchronous UART.
- Easy plam Protocol developed by the author.
- Protocol with collision detection and verification of transmissions.
- Communication speed of 19200 bits per second.
- Maximum working distance of 1200 meters (RS-845 standard).
- BUS Network topology.
- Up to 32 units uHomeLan (by Bus home automation).
- Up to 253 units network uHomeLan, with expansion switch.
- Address programmable network-based units uHomeLan 1-254.
- Network cable 4-pair UTP 22 AWG Standard.
- Standard RJ-45 connectors.
- 24V low power supply voltage.
- Power through the network cable (Power over lan).
- Developed Firmware for AVR-8 and MCS-51 microcontrollers.
- Distributed programming in all units or central home automation uHomeLan.
- Direct programming through the network.
- PC Software for control and programming.
- Intuitive software for program development through the Web-site http://www.microhomelan.net.
- Units uHomeLan or central home automation modules, divided into motherboard, cpu controller and regulators.
- PCB, printed circuit boards developed on one side, to facilitate construction and minimize the cost.
