Outdoor temperature sensing

Currently I am using an Air Quality Egg for outdoor temperature sensing, but I want to deploy another system and it needs to measure outdoor temperature.

How are people doing this? Indoors emonTH with an external DS18B20? Put an emonTH in another case?

The most resilient way I've found is to mount the sensor board emonTX/emonTH in a waterproof 'electricians' wiring box (Toolstation or Screwfix) and attach an encapsulated DS18B20 sensor, sealing the exit hole with silicone.

I built mine using just the emonTX pcb as you would not need the full functionality of a fully built emonTX.

Mine's stood outside in the wind & rain for the past 6 months and has worked flawlessly.

Thanks, that was pretty much the route I was going down. I'd like to try to find a smaller waterproof case - even the smallest wiring boxes are quite chunky!

I used 'schneider' boxes from Screwfix, they are IP55 rated which suffice in all but extreme conditions. Not sure what size I used, but they do a wide range.
