I want to make a bms home system with 8051.But i don't know wich microcontrollers to use.To be specific i need a: 1 microcontroller that can communicate with wifi because i want to control the entire system via my pc b:unknown number of microcontrollers which they were connect with the wifi microcontroller.Also in these microcontrollers will connect the d/a and a/d converters for the sensors.
*For this project will i need any other chips except controllers,converters and the "typical" max232, etc...? *To make the network between all the controllers which protocol do you recommend?will i need specific controllers to make the netwrok?
plz help.... Thanx
You can try googling for ZigBee.
But it is an intelligent standard for home automation. Small, cheap radio modules normally intended to be installed in every controlled node and possibly driven by batteries.
The ZigBee standard also has routing capabilities, so one ZigBee module may forward data to other modules further away, in case the PC is out-of-range to some devices. But that requires that you have modules with this routing functionality.
Read more here en.wikipedia.org/.../ZigBee
Note that you also have links to other standards from that page.
Have '51s with avaliable canned Zigbee source.
