Sensing and Control for hobbyists and schools

These pages are intended take you into the fascinating world of electronic sensing and control. A very, very simple example of the sort of thing you'll find here is home heating control: Something SENSES the temperature in the house, and then CONTROLS the heating, turning it on or off as necessary. Making something to hunt for life on Mars is, in principle, nothing more. Visit the "Examples" link below, too.

Happy study....

     Sensors: Electronic thermometers and more.
     Actuators: The devices which make things happen.
     Connections and wiring: Information on connecting everything.. locally and across LANs & internet.
     Programming: How you establish the rules.
     Burglar and Fire Alarm Systems: Some specific considerations.
     IpCams: Iot ("Internet of Things") devices which give you video or still images across a LAN, or across the internet.
        ("IpCam": Internet Protocol camera. Some offer audio, digital inputs, digital outputs. Great fun! Super sensors! $30 on eBay.)
     Examples: Click here for.... (You can guess.... I hope!)


Combining many elements of sensing and control, I hope you will forgive my enthusiasm for a family of products I have created and call FarWatch.

If you have premises with an always-on broadband connection, you don't need to pay for anything more to set up a system that lets you monitor those premises from anywhere on the internet. Some configurations allow you to record the data. The monitoriing can include weather conditions... or whether your house's heating has failed, and you are on your way to frozen pipes. (A "pipe watcher" can be implemented for $30).


This web resource has been evolving since September 2002. You can either find things through the links, or use the search button below to look for something specific.

If you would like to use material from this site, say on a CD, my page about permitted use may save you some time.

The search engine merely looks for the words you type, so....
*    Spell them properly.
*    Don't bother with "How do I get rich?" That will merely return pages with "how", "do", "I"....


Please also note that I have several other sites. This search only looks through my Sheepdog Software pages. The other sites have their own search buttons.
My site at Arunet.
Help with the excellent database which is part of OpenOffice/ Libre Office, at my SheepdogGuides site.
The Google search at the top of the page searches all three sites for you.

Ad from page's editor: Yes.. I do enjoy compiling these things for you... hope they are helpful. However.. this doesn't pay my bills!!! If you find this stuff useful, (and you run an MS-DOS or Windows PC) please visit my freeware and shareware page, download something, and circulate it for me? At least (please) send an 'I liked the parallel port use page, and I'm from (country/ state)' email? (No... I don't do spam) Links on your page to this page would also be appreciated!
