How can I remotely turn on and off the heat to my ice house within a 2000 meter (1.243 mile) radius?
In order to turn on and off the heat at the ice house,
I would have to turn on the propane tank outside and then go inside and press the on button on the heater.
My current plans are to create a machine that would turn on propane tank outside and another machine to press the on button inside. I would connect the two machines to a wireless receiver. From this site (http://www.rfcontrolsystem.com/index.php?cPath=173), I learned that in order to extend the range, I would have to use a wireless relay (I’m not certain if it would be AC or DC). I know I have to use a 5000 meter relay because of interference. I would like to have two remote controls for one receiver, but I’m not sure if that’s what channel means in 2 channel versus 4 channel AC/DC power supply in the 5000 meter remote control kits.
My main questions are:
Would a receiver online time and the two machines take up too much battery power that the project wouldn’t be worth the 15-20 mins of waiting in the trailer till it warms up?
Is this the proper plan of attack for a project like this?
Would I use AC or DC power?
Does having two remote controls mean having two channels?
Any help would be greatly appreciated, thanks.
Do you have a clear line of sight for the 1.2 miles and always come from the same direction every time? I would use 2.4GHz WiFi with high gain directional antennas and either a Raspberry Pi or Arduino to do the rest. This would give you 2-way communication instead of the 1-way with a remote.
2 channel means 1 remote controls 2 relays. If you get something in the 300-500 MHz frequency, then you could use a UHF TV antenna to increase the directional range more than the omni-directional will give you.
If you're running this off a battery, then make sure everything is DC. Using an inverter to make AC ftom DC is inefficient.
Battery consumption should be less than 50ma, so just power it off a deep cycle marine battery and add a solar panel on the roof or a wind generator if you need longer duration. If you're an ice fisherman you probably have a boat you can borrow the battery from.
