Temperature sensor fridge

Post by DJF3 »

Team,

I'm looking for a temperature sensor with external sensor for my freezer.
Is there anything rfxcom compatible for sale right now? (In the Netherlands)

Cheers
DJ

lots of them not available anymore thc238 should be the successor, but also hard to find
I use the thc138 which works fine, but they are older now :(

Dag Bert,

Is this device not supported on the RFXLAN?

RFXLAN supports only Oregon sensors.
You can use the internal sensor of an Oregon sensor and extend the connection with a thin 2-pair cable. Isolate the sensor with a 2 cm heat-shrink tube.

I've an Oregon sensor just IN the fridge, after 1,5 years no issues so far.

The signal doesn't reach my rfxcom from within the fridge :-(

Will try Bert's suggestion to extend the sensor itself. I may have to calibrate it after taking it out of the original casing

I opened a typical (simple) Oregon temp sensor. WOW!
The wires going to the temperature sensor are as thick as a hair!
Not sure I can extend that with my soldering :)
