This replacement case allows the Sonoff SNBN-02 to be use on a water pipe to measure the surface temperature of the pipe. I use this to monitor the performance of my central heating system.
I have compared the Sonoff with analogue pipe thermometer and it is always 5 degrees less then the thermometer.
I am planning to create an L-shaped copper heat sink and attach it to the sensor with a drop of thermal paste to see if that improved the accuracy.
The current is for 22mm pipe, I am planning a 15mm version soon.
Update 11 Jan 2021
Old one does not quite fit correctly. and i have reduced the amount of plastic a bit to help tie it on to the pipe.
I have added a slot to allow space or an 'L' shaped piece of copper 1mm thick to act as a heat sink. Use the 'no-heatsink' file if you don't plan to use a heatsink so that the sensor sits very close to the pipe.
