Topic: Beware when trying to spider-proof the WS-2902 (for dummies like me)

[Y42351]

Noticed that the rain gauge wasn't working, so I cleaned out the spiders and webs from the unit. As an extra layer of prevention, I sprayed bug spray inside the rain collector where the paddle is. I was shocked to see a temp reading of 140F with a 99.9F dewpoint when I looked at the display, plus the UVI/lightmeter had stopped reading! Worried that I toasted my sensor, I thoroughly blew canned compressed air throughout the sensor unit, and thankfully, everything went back to normal.   

Now, if I can just get WU to edit my data....   Ambientweather's site was no problem to edit.

I don't know if a mothball will fit inside your Ambient but Acurite suggests this for their 5 in 1 units if their is an insect/arachnid problem.

That's a great idea! Should be plenty of room in there! Thanks!

You're welcome. I'll be doing it when I take mine down for maintenance in advance of the insect brigade.

Just about ANY oil-based "fumes" can/will contaminate most RH-sensors.

So, is there anything that I can place in the sensor area to repel spiders that won't mess up the RH sensors?
