remote thermometer ideas?
heatbank in an attached barn with attached mechanical temp gauge
mounted in/on it. Would be a *lot* more useful if temp could be checked without going outside and into barn - any suggestions (and sources) for some sort of suitable "remote temp gauge" - temp range say abt 30 to 90 deg c - wired is fine tho if cheap wireless acceptable :) - (don't fancy the car type umbilical even if accurate.... cheers JimK |

I have one - the remote sender doesn't have a great range, but is better with clear line of sight. Does do Min/Max which may be helpful. There's probably better stuff... Some RS232 gadget with a temp sensor (can give you hints if that's of any interest). RS232 travels quite well at low bit rates (2400 will do 100's of yards. Jack into PC in house. ? -- Tim Watts This space intentionally left blank... |

One wire sensors are cheap and easy to use, have few and a cheap PC and log what your heatbank is doing. Inputs outputs etc. -- Cheers Dave. |

I had a trawl on fleabay and these for e.g. :- itemno 260531949471 look ideal - except I would need to extend the cable to abt 5m - any comments on whether that would work or would extending cable by 500% bring other snags into play?

Cheers JimK Can't be absolutely sure - that could be an analogue sender in which case dodgy long wires may throw the reading out but it will still generally work, or it could be digital (eg 1-wire) and not read at all if it gets unhappy, though 1-wire specifically will easily do 5m - it can do a lot more with decent cable. However, for 5m, I really don't see a problem. I would deploy some screened twisted pair cable (eg mic cable, STP network cable or any reasonable stuff you can get your hands on). Then suck it and see. Do a calibration check against a known thermometer and if it gets wibbly, try earthing the screen at one end or the other. -- Tim Watts This space intentionally left blank... |

The cable appears to be twin so I'll see what happens and report back. 4 inches of snow by lunch today!! Cheers JimK |
