====== Project OrBit ====== This project's aim to develop a home automation device to [[https://en.wikipedia.org/wiki/Home_automation|monitor/control]] a variety of device in home or office depending of the user’s requirement. Modules will communicate with each other [[http://www.silabs.com/products/wireless/EZRadioPRO/Pages/Si446x.aspx|wirelessly]] or via [[https://en.wikipedia.org/wiki/RS-485|wired protocol]] . A interface will allow further customization option for specific user's task/requirement. ---- ===== Presentation ===== [[Boards:]] will consist of a [[nodes:core]] and [[boards:|module(s)]]. All [[nodes:core]] will be the same to facilitate developpment, but [[boards:|module]] will change depending of the usage. A smart implementation of [[https://en.wikipedia.org/wiki/Mesh_networking|mesh]] inspired network will allow device to interract with each others, wheter it be [[https://en.wikipedia.org/wiki/RS-485|wired]] or [[http://www.silabs.com/Support%20Documents/TechnicalDocs/EZR32WG330_DataSheet.pdf|wirelessly]] ---- ===== Synthesis of objectives ===== - [[boards:|Module]] should be able to upgrade their firmware using existing network capability - Automated task should be customizable via an interface - Communication must be transparent to user application ---- ===== Goal and expected results ===== - Automate task based on environmental or time-based trigger - Create task with a dedicated user interface - Firmware upgrade propagation through the network - Node interconnection available even without direct access (mesh) ---- ===== Planning ===== - Project requirement and goal - Basic Wiki for documentation - Happy gecko test for user introduction - [[boards:mantle|Mantle]] version 1.0 - Firmware upgrade from auxiliary memory - Basic wireless communication - Basic RS-485 communication - More later ===== FCC Standards (Legals) ===== * [[https://en.wikipedia.org/wiki/List_of_WLAN_channels|Available wireless band]] * 902 to 928 MHz (chosen band) * 2.400 to 2.4835 GHz * 5.725 to 5.875 GHz * [[http://www.afar.net/tutorials/fcc-rules|Maximum transmitter output power]] * Fed into the antenna: 30 dBm (1 watt) * Effective Isotropic Radiated Power (EIRP): 36 dBm (4 watt). ===== Annex ===== This is a rather large project, the main goal is to provide a standardized interface for communication and data gathering.
