I’m writing this post as something I plan to update after field testing, and since this question has been bugging me for months. I might have a design flaw in a recent prototype, since I mostly neglected temperature considerations in a PCB design. What is the temperature inside a weatherproof box in the middle of summer? Does it exceed the 65 degree limit? Does anyone have experience with this?
Today, I shipped out some devices (custom designed relay controller inside a weatherproof grey box with clear cover) to my test location (dry, arid, west Texas), but with an additional tmp36gz temperature sensor inside the box. The temperature can routinely hit 100 to 110 degrees outside in the summer. I plan to test the device in three different ways. All devices are clamped to the side of a metal electrical box using magnets.
- Device on south side of electrical box, full sun.
- Device on north side of electrical box, should be shaded during peak heat.
- Device on south side of electrical box, but with rag or other cloth on top taking the direct sun.
If you have experience in this chime in, otherwise, I hope to report back in 1-2 weeks with results (weather dependent).
