New soil temperature sensors

Due to the very cold weather we had in December, -15C and below, my soil temperature sensors didn't hold up.

The sealant i used (brown frame sealant) deteriorated in cold - which is bad for anyone using it to keep their windows in !

So now i have set the sensors in the same 7mm dia. copper pipe, but only used 50mm long pieces.  Hopefully the HMA (Hot melt adhesive) - more commony know as hot glue gun stuff - will keep the water out.

Initial testing showed the sensors reading 35C and 37C while the glue cooled. :)



Now i have to come up with a method to connect the sensors back to the cable i removed them from - last time it was all one piece.

    When searching for 1-wire soil temperature you have made number 4 on the list ;-)
