Decided I need to move my sensor...
« on: May 23, 2015, 10:32:08 PM »
So I've decided I need to move my 5 in 1 sensor a little higher. I'm getting temperature readings that are higher than my tower station in the front yard during the day. I assume it's because the sensor is so close to the roof that the shingles are generating heat due to the sun and tampering with temperatures around my sensor. I figure if I move it higher it will improve temperature readings by not being so close to a black surface and solar panels will be more exposed to sun. Also wind readings will likely be better. I know that in doing this my rain readings will be off but I have a CoCoRaHS gauge anyway. BTW thanks to everyone that replied to my last post and suggested all these things. So now to move it. Currently it is only the given mount attached to a car port (basically a flat roof). Anyone have any suggestions on how to mount it? Also if anyone has any DIY ideas go ahead and post I really dont feel like spending $100 for a mount or something crazy like that so DIY would be appreciated too :D Also drilling holes into the roof is not something that I can do. Thanks in advance!

This is the downfall of the all-in-one weather stations in general, but usually with a little experimenting you can find a decent compromise. Wind speed readings take the biggest hit, but even with discrete sensors most of us can't get the elevation that is needed in a suburban environment. I have two tower sensors in addition to my 5in1, and it is amazing to see the differences in the small micro-climates that exist around the average house. This is really part of the fun, and enjoyment for me though. Always an ongoing quest.

I took a look at you PWS. I see you have it mounted on a pole that is attached to some wood. May I ask how high up is that? Might take it down from roof and do something like that.

It is right at 12 feet. I am going to have to come up with something else soon. I used treated lumber, but it is starting to twist  on me. I keep having to shim the mount to keep thinks level. I think I am going to create a telescoping pole out of some heavier pipe, and set it in a concrete base.

I might try something like your setup in my front yard. I just need to either get it higher above roof so that heat doesn't affect it and wind readings are better or put it over grass but then it wont be high enough for wind. Man living in the suburbs is hard :(

Jack, I have my 5in1 mounted 9' high on a galvanized pipe bolted to a wrought iron fence post.  I'm wondering whether the pipe itself absorbs enough heat from the sun to affect the temps shown by the sensor.

Haroldashe, I have the same setup as you except I attached a three foot piece of schedule 40 1" PVC  to the galvanized pipe to compensate for the possible heat transfer.
