Thanks Tansis for sending me a schematic,but i like to ask as you mention here A cell-phone interface might do the job, depends just how far you mean by "long Range"
so how i do with my cell phone please Answer in detail
If you check the "CK1618A" you will be able to view all info on a 10 channel Rx & Tx listed at 69.95 for the assembled unit.
I've check the range on this devise and although they claim 120 ft I got as much as 250 ft. It's in the UHF frequency, so it will have no trouble going up through six floors of a building.
You can get the code on how to trip each of the 10 channels from **broken link removed**
