plug-in thermostat with probe?

Glaucus · 01-03-2011, 21:44

Was wondering if you kind folk could find me a gadget.

Looking for a plug-in thermostat with sensor probe.
One where you plug the thermostat into a wall then a device/heater into the thermostat. Any should do as long as it covers the 10-20c range which I imagine any would.

Like this but english 3pin/240v

Can find loads without a probe and a lizard tank one with a probe, but it has variable voltage rather than simple on/off.

Any help would be much appreciated.

There's a thermostat kit near the bottom on this site.

Will that do the trick?

Unfortuatley not, needs to be main powers. What I want is to connect a fridge into it.

How do you mean? You can run that 'stat off a transformer. If you need it to switch the fridge on, you can send the relay output to something like this to then switch mains voltage...

hum tbh I'm not very good with electronics, no problems soldering and following plans, just not doing any of the thinking part.

what I wanted was a thermostat which plugs into the wall socket, you then plug the fridge into the Thermostat.

with a 12v thermostat how would you then control the fridge at 230v?
does that splice into teh fridge lead and you then attach the thermostat to the relay?

Ummm... sort of...

By the look of it, the stat has a 24v relay. This to me says that when the desired temp is reached, it switches on a 24v output from its relay (but is itself powered by a 12v source, it probably sends two 12v feeds in series on the relay, giving 24v output, or something).

You would then connect that 24v output to the input on the second relay (the one on eBay). When that receives the 24v feed, it will then switch on it's 240v feed, on the other end of which lies the fridge.

It's not as elegant as a single device, but you could mount them into a plastic box easily enough...

In fact, with a little shopping around, you could probably mount a plug, a socket and a 12v jack socket to a plastic box (or even better, place a small 240v-12v transformer inside the box), and mount the gubbins inside, giving what would look like a thermostatically controlled extension cable....

p.s. If those things do what I think they do, I could make you something at cost, if you like?

Thanks for offer, not looking for anything straight away though. Just spent loads on chilli growing equipment.

lol, hydroponics.... careful who sees that kit..
