Perseus Posted November 25, 2005 Report Share Posted November 25, 2005 HelloI am looking to make an exterior light remote control so my wife can turn on some exterior lights when she drives up the driveway, maybe 200 foot distance. (We live in rural area and she gets nervous)I am not sure what way is best. From what I have read through these forums, IR seems to be limited in distance and obviously line of sight, but easier to implement.RF seems to be longer range but more involved.I am willing to take on either way if I can get some opinion on what method to use.ThanksScott Quote Link to comment Share on other sites More sharing options...
audioguru Posted November 25, 2005 Report Share Posted November 25, 2005 Hi Scott,Ir is simpler and if your wife has a good aim, then a laser pointer will go pretty far. ;D Quote Link to comment Share on other sites More sharing options...
SupeR-NovA Posted November 25, 2005 Report Share Posted November 25, 2005 but you have to be quite good to aim at a sensor which is 200 foot away, WHILE DRIVING!!you should use the RF method...there is quite alot info on this on the web, it shouldn't be to complicated...

Perseus Posted November 26, 2005 Author Report Share Posted November 26, 2005 LOL good aim huh?Guess I better stick to the RF.Thanks for the input, time to roll up the sleeves! Quote Link to comment Share on other sites More sharing options...
Shahriar Posted November 27, 2005 Report Share Posted November 27, 2005 HiIf you want to build a RF Remote control, i Think theis project will work fine. I have not build it yet but its design looks perfect. It belongs to 27MHz Toy Car.http://jap.hu/electronic/rf.htmlHTH - Shahriar Quote Link to comment Share on other sites More sharing options...
wood_workur Posted November 28, 2005 Report Share Posted November 28, 2005 What if you had a light sensor on a tree near the front of drive way? Quote Link to comment Share on other sites More sharing options...
Perseus Posted November 30, 2005 Author Report Share Posted November 30, 2005 ShahriarGood link, thanks. I will have to study those for sure. When they state a 500 mm Antenna, can that be wound or does it have to be straight?A remote light sensor? I had not even thought about that. interesting.Thanks again for the tips.

Shahriar Posted December 2, 2005 Report Share Posted December 2, 2005 Dear Perseus Antenna theory is very complicated and any Shape antenna has its own specification and uses, but as I have seen in some SIMPLE remote controls, the Antenna shape does not have very Specific impression on the range. I am going to build it for some one, If I did it, I will tell you about the antenna shape....HTH - Shahriar Quote Link to comment Share on other sites More sharing options...
