Hi people,I live on a small acreage and I have two wells and two pump rooms onthe property. Winter temps frequently get below freezing so I have tokeep a small heater in them to prevent pipes freezing overnight.Currently I use some cheap indoor/outdoor thermometers to monitor thetemp inside the insulated enclosures but I have to walk to each one tocheck it.I need some temp senders so I can have a remote station in the houseand each one can constantly indicate the inside temp so if the heaterdies I can get down there and fix it. I can have a switch to cyclethrough them manually I do not need a 4-station setup but that wouldbe a nice luxury, cost permitting.There is 110v in all places so batteries are not an issue. Can anyonesuggest a CHEAP kit I can get? The farthest away sender would be about800 feet.Thanks in advance.--Kind regards, Jenny and her tribe of survivors.

This is probably overkill for your application, but I sell a kit of my own design that can do that...It's really intended to be used over amateur radio, but if you don't have a license you could probably use it with a radio on one of the nonlicensed bands. MURS, maybe - I'm pretty sure telemetry is forbidden on FRS and GMRS.I've got a number of users using these for temperature and voltage monitoring on remote mountaintop repeater sites. The cool part is that if you do have a ham license (easy enough to get), you can use an existing nationwide APRS network on 144.39 MHz that'll get your data onto the web. And because I've got so many people using these things for enviromental monitoring (I originally designed them for GPS-based vehicle tracking) I'm working on developing an email notification system, so you could be notified when the temperature crosses a defined threshold. That's assuming you're on the APRS network - standalone, you'd have to run a receiving station yourself.Yeah,...

Remote temp sensing help??

Hi, a new technology is out there that really can help this problem. It involves meshing or linking multiple radios to each other to relay the data. Here is link on how it works:
