FS20 Magnet Ventil Controller

FS20 Magnet Ventil Controller

For automation in home and garden a remote controllable set of magnet ventils are always needed (i.e. for garden watering, etc.)

magnet ventils

there are a variety of magnet ventils. I already have some industrial ones in use. But the gardena 24V ventils seems to be a cheap and reliable alternative. (product details on gardena page )

controller

In particular the controller will be a multi channel relais driver beeing able to switch a series of devices. For a high level of modularity the controller is relaizes as an own module providing an I2C interface (and probably RS232). The core of the contreoller is based upon the cheap and very suitable atmel avr AT90S2313 (see description on mkrocontronner.net )

The controller will however support the following modes for every channel:

• switch on/off
• switch on for a given time
• request current status

remote control

An advantage of the modular design will be that the controller can be used for a variety of scenes:

• FS20 remote controller
• direct connected to PC (Serial RS232, USB)
• XBee (or any other) remote controlled

For the proof of concept a FS20 based remote control mechanism will be set up based on CPM module from busware.de
