While I am waiting on the project box to come in I thought I'd put together something I have been thinking about for months.
After reading many, many threads on how and where to mount senor probes I thought maybe a sensor pouch with a strap might work.
First gathering up some things I had around house.
A soft bag that a replacement rear view mirror came in, some velcro strips, and some bubble wrap.
Cut out a square patch of bubble wrap that would fully cover the sensor.
Using the bubble wrap as a guide I sewed a square shape giving wide berth around the wrap.
I cut the square shape out and put the extra material to the side. I used white thread on purpose so it would show up well.
Sewing down both sides give me a perfect pouch for the bubble wrap to slide into.
I want to sew a few 45° seam on each side of the velcro so I use it as a guide from where to get me started.
I decided to tack the strap directly to the pouch so there would be even pressure right over the back of the sensor.
The sensor needs to have direct contact with the glass of the carboy so I cut a small window in the face side of the pouch.
It fits pretty well.
You can see the sensor has contact with the glass.
