Can anyone recommend a cheap waterproof "plug" to use for wiring an external sensor to a case-enclosed arduino?
I'm planning an outdoor application where the arduino sits in a waterproof case, exposed to the elements, with up to 12 4-pin analog sensors individually extending from the case. The arduino will be wired to 12 female plugs on the inside of the case, and the actual sensor/cable will connect via a male plug on the outside of the case. Not all sensor plugs will be used, so I need to plug to be waterproof even if nothing's plugged into it.
Googling finds tons of plugs, but most are $20-30 a piece and designed for high-end industrial applications. Where would I find something cheaper, geared more towards a consumer application?
use some chewing gum to fill your holes. or cover the whole thing with spray on foam insulation and paint it to look like a rock. this is my junction box. i even stuck moss on it. i cut out a cupholder in the top corner. someone i know said "why is their a big cement block over there?" i said its a rock. it fooled him...lol
