Current best practice for Temperature and Humidity?

There are quite a few out there with online systems, and a few different options for temperature and humidity.

Looking for input from users as to what sensors work best for inside the hive.

Is there much of a real-world benefit to monitoring humidity?

The hive temperature/humidity

The hive temperature/humidity sensor should be placed in the center of the brood nest if possible. If using 2 double deeps - place it between them, if you are using 3 mediums like I do, place it between 2nd and 3rd box.

As always, the more data the better. You can tell when the bees are bringing in pollen or nectar and whether they are curing the honey by correlating the temperature inside of the hive with the weight and humidity.

Hard to maintain?

How hard is it to maintain in-hive sensors? I'm guessing that the bees will propolis the sensors very readily and not sure how this would effect accuracy. Do they require constant cleaning?

DHT22 Temp/Humidity sensors - tips

I prefer the raw DHT22 sensors they are small and inexpensive. They don't like to be wet which has been challenging for me for ambient temp & humidity. In hive they do get propolyzed, I've put some in small plastic queen cages to prevent blinding or every 3-6 months clean the pores with a pin as needed. For ambient I tack to the underside of the hive. I get 5 for $16 on Ebay and consider them a throw away.
I don't feel the information is critical but the cost is minimal and it only takes me about 5 minutes to assemble one on a cable with phone plug. If you use the Temperhum USB (I don't), I recommend applying a small ammount of silicon grease in the connection and tape well as they oxidize readily.
I've learnt not to pull the cable up through the entrance, I notch the hive body rear center to fit phone cable above the brood box and place sensor between the frame top rails. A bit outdated but details may be seen here http://hivetool.org/w/index.php?title=NAPAPi

I tried wrapping the

I tried wrapping the TEMPerHUM in window screen. Probably a mistake. They get heavily propolized. I believe some folks harvest propolis using something like screen so what ever they do, do the opposite.

DHT 22 protection

As someone suggested in a different post.(before this forum) I'm going to try hair rollers.

These fit really nicely -
Diane Snap-on Rollers * 3/4 Inch * 12 Rollers Per Bag
http://www.amazon.com/Diane-Snap-Rollers-Inch-Bag/dp/B0027CDBN2?ie=UTF8&...

This setup will fit easily through a 1 inch entrance hole if you don't really want to put a notch in your supers. They fit either between frames, or can fit between supers... it's your call.

I closed off the top and bottom with small zip ties to keep those gals out completely isolated from the temperature sensor.

Did you have to flatten them

Did you have to flatten the rollers? In the pics they look flat. Maybe it's just the result of the zip ties. I'd be curious to know how well they work. I've always had lots of problems with my bees wanting to cover anything plastic with lots of burr comb.

Rollers over temp sensor

The rollers are just barely big enough, so you kind of have to squeeze them to get the sensor inside of it, then putting the zip ties on it flatten the ends a little more.

I had a complete late summer die-off, so no bees right now. In Minnesota my bee supplier has not yet delivered 2016 packages, so I can't tell you how it works in real life - I can post back in a couple months.
