I will do a test in my house today. I will you comment my results. Maybe we can solve the problem of the cable with a thicker cable. I will do a test in my house today.

]]> Comment on Arduino and relay, or driving 220V devices with Arduino by tochinet http://www.ogalik.ee/arduino-and-relay-or-driving-220v-devices-with-arduino/#comment-315 tochinet Wed, 19 Oct 2011 11:48:32 +0000 #comment-315 Actually, if you want to command 220V (or anything else) from an Arduino, the easiest and likely cheapest solution is ... to buy a ready made board. On eBay, you'll find 2-4-8- or 16-channel relay boards, working on 5V, 12V, 24V for less than you'll have to pay for the parts alone. Regarding the original drawing above, I wonder why there are 4 resistances in series, since this is all low voltage. Since there is galvanic separation in the relay, you also don 't strictly need to add the optocoupler, but I agree this is safer.

Works reliably. At least I can see no difference between 20m cable and 50 cm cable. It is not a phone cable actually. I did get it for connecting security system sensors, but it can also be used for telephone cabling. The price class was about the same and the cable is almost the same. Actually CAT5e or better should be a lot better cable. I'm planning to add some more sensors and using CAT5e this time. If You look at <a href="http://www.ibuttonlink.com/linkusb.aspx" rel="nofollow">linkusb</a> then 1000 feet (approx 300m) on cat5 should be doable. Maybe not with straight connection to arduino, but doable. I do have one DS18B20 connected with a 20+ meter cable. Works reliably. At least I can see no difference between 20m cable and 50 cm cable.

In that way, can I imagine that any 1-wire captor will be able to be read at about 20 meters far away from the board. My project is to put some arduino in my house to collect captor data and I'm in the phase of testing captors to ensure max length from the board to the captor in order to know if I have to put an arduino in each room or at each floor only... Thanks for your feedback, best regards, Jérôme.
