Well done and nice Job Derek!
I'd be looking at insulating those Temp sensor leads though (or get the female connector).

Hello Uncle Bob.
Many thanks for your comments.
I was concerned that the sensor (sht21)would not work on my cable, which is just over 2 mtrs long.
In fact it works fine.
So it is a very temporary hook-up.
My next step is to make some sort of shield for it and tidy up the wiring.
Best Regards Derek.
