I need a single on/off data line transmitter / receiver with a range of around 1000 feet.
It can transmit a status (on/off) once every 2 or 3 seconds and must be operated by batteries and if possible around 418MHz. I do not have line of sight.
I found the simplest solution to be from Linx Technology using TXM-418LC, RXM-418LR and using their encoder chip LICAL-ENC-LS001 and its matching decoder.
Perhaps the simple solution is the most expensive specially for the $15 RX chip.
Can anyone guide me to a cheaper solution?
It doesn't have to be as simple as above but my device will operate outside at temperatures between -30F to 90F.
