Sorry for delay in responding. The house is being built at the moment. It was designed by Roger Buck and contains many tons of concrete to achieve thermal mass. Is extreemly well insulated.
We have a sunspace to receive most of the solar gain. The hot air rises and is either allowed to leave through a roof window (electrically operated?) or circulated to the extremities of the house using fans and ducts. Due to the problems inherent in cabling a concrete house we opted to do our switching using relays at the switch board and using cat5 cable to the switching points. I have built touch switches and an interface to the relays. The interface to the computer is via a series of boards from Weeder electronics. These connect to an rs232 port. With this setup the computer can monitor and/or control anything that is switched in the house. Fans, window openers, Towel rails, undertile heaters, kids bedroom lights. For sensors I only need a few temperature sensors. scattered through the house. These are built from cmos temperature sensor chips $6 each. (The chip and a couple of resistors are soldered onto the end of the wire.)These convert temp to mV which is read by a Weeder Electronics A to D interface. I would like to know what the wind is doing and the sun but this can probably be infered from the effect on temperatures. I need to know when it is raining but, until I find a cheap way to tell that, I will have to keep the roof windows closed when the solar input is low. Most expensive single item will be the window opener. Don't know how much as its part of the house contract. $200 each for 2 fans. Weeder interfaces are about $US40 for about 10 bits of i/o. I think this is pretty good. The boards are realy easy to talk to. I spent about $600 on interfaces $350 for a second hand PC to be the house server $0 for Linux $??? for Kylix Home made touch switches are a bit cheaper than standard switches but don't look to flash. $900 for electronic components and relays Circuit boards were drawn using Open Office and produced at Printed circuits Ltd in Christchurch. About 50 hours soldering it all togeather. This gets about 40 switched devices and 20 switching points capable of up to 4 switches and 4 temperature sensors Steven > -----Original Message----- > From: Leigh Wanstead [mailto:[EMAIL PROTECTED] > Sent: 03 November 2003 12:37 pm > To: Multiple recipients of list delphi > Subject: RE: [DUG]: [DUG-OFF-TOPIC]: Any Kylix programmer? > > > How do you read sensors?
