A Very Good Product
Rating:5 out of 5 stars
This little gem does exactly what it’s supposed to do, reliably and without any fuss or bother. I have one in the basement to monitor temp and humidity and another outside. The outdoor unit has endured all sorts of nasty New England weather and it’s still going strong after two winters, blizzards, wind, sub-zero blasts and enough rain to make me consider taking up ark building. If you have the requisite receiver to display the remote temp and humidity, this is the ideal sensor to go with it.
Good thermometer
Rating:4 out of 5 stars
I had wanted an indoor outdoor thermometer for a long time. Then I found this one on Amazon’s website and ordered 4 of them. The other 3 I gave away as gifts.
The one thing I don’t like is that you can’t see both indoor and outdoor temperatures at the same time. The accuracy seems good within a deg or so. Hard to judge the humidity accuracy but seems to be fairly close. Another thing is if you live in extremely cold areas you will need lithium batteries for the ouside wireless unit. So I rated this 4 stars.
Superior Product
Rating:5 out of 5 stars
This is just great for keeping track the temperature & humidity. Purchased one here in Arizona
last year & loved it so much have now purchased another for our home in Canada. Have had the remote
outside in freezing weather & over 100 degree temperatures. Can even have up to 3 remotes
Poor Reception
Rating:1 out of 5 stars
This sensor has a very short range (well under 100 ft.) and does not work at all with the alum. siding on my house. While the accuracy appears to be acceptable, I did not compare it to a more accurate device. Honeywell should take a look at their claims and change them with regard to my findings as all three of my sensors performed in the same manner.
Remote temperature humidity sensor
Rating:5 out of 5 stars
I am quite happy with the TS33C remote sensor. It started to work with my existing network immediately, and it has remained in reliable communication. I appreciate the rapid and reliable service by an Amazon partner! (th)
Works great, plug and play with my honeywell weather station
Rating:5 out of 5 stars
Product works great, I simply set it up and set my weather station to search for more sensors and it found it. I like the ability to monitor different locations with the same weather station. I think I’ll get another one in the future.
works great!

works very well, see my review on the main unit, only down on this is the display is small, but with the main unit, its perfect
Seems to be fairly accurate
Rating:4 out of 5 stars
I bought this to add to my Honeywell TM005X Wireless Thermo-Hygrometer which can monitor up to 3 remote stations.
I had purchased a wireless therm-hygro unit from WalMart earlier this year, but wasn’t impressed with the quality and their accuracy. Took them back and ordered the TM005X with this additional remote. IMHO, the Honeywell units are much better.
I have the base station and 2 remotes. I’ve installed new foam insulation and an unvented roof in my new remodel. I use them to monitor temp and humidity in my basement, main floor and attic.
You line them up in the same room and the temps are all within 1 to 1.5 degs and the RH are within 2% to 3% of each other. I haven’t calibrated the units yet, but so far I’d consider them a pretty good value.
