I have a plan to put together small home automation system.
For now I was just playing with smaller parts like single type of sensors at once etc... I would like to ask for opinion & check of my scheme if basic idea is ok, before I plug everything together. I saw many variants of externally powered Relay Board, so I am little confused and I am not sure if its ok.
Basic idea is to see data & control everything from website DHT sensors (read and display data on website graphs) - only DHT22 nr1 will trigger PC-FANs 1 & 2, when temperature or humidity is too high PC-FAN (1 & 2): they run ON all the time (set time from ... to ...) LED strip (1 & 2): they run ON all the time (set time from ... to ...) (LED strip has to be on separate power line since current A is to high for single relay) Soil sensors (1-4) (read and display data on website graphs) Water pump (1-4) each separately triggered for period of time when humidity in soil is to low (from Soil sensor 1-4)
Any suggestions are welcome, thank you.](http://s31.postimg.org/b06n6k8t3/HAS_sheme.jpg "[/url]
