 Different (Good) Experience w/ Batteries & Performance January 17, 2010

I was originally given the WS-9023 Weather Station as a gift (with this single sensor). I have since bought two more sensors through Amazon for use with the system. First, all units sitting side by side give the same readings within 0.1 °F (all emperiments should be repeatable...they should fail in exactly the same way). In addition, I have an airport with a reporting weather station less than 0.5 miles away and have found that the readings I get are very close to what the local airport weather station reports.
Unlike other experiences with battery life, my experience with battery life have been outstanding. Anticipating that I would have to periodically replace the batteries in all units on a reasonably frequent basis, I used rechargeable batteries in all units. That was July 2008 and they are still running on their original charge. But battery manufacturer apparently does make a difference, given the various rechargeable batteries that I uae. I have one unit mounted outside, one upstairs and one downstairs in the house. Range of signal does not seem to be an issue for me at least around the house.
As a practical limit, the electronic hygrometer can only read as high as 89.1% even in a zero visibility fog.
Very pleased with the performance overall.
works perfect December 2, 2009

We replace an old sensor that got water damaged. The new one works great with the base unit.

The fact that this product does not have any display makes it difficult to test for accuracy. In addition the range of communication with the central system in the house is somewhat limited... It was not performing accross a concrete wall and I had to relocate it near a window.
it does what its supposed to March 5, 2009

just make sure you have the a 915 MHZ base unit to communicate with this wireless sensor. some other base units are 415 MHZ(not sure of the exact number). it comes with plastic cords to attach it to a hole. I believe the manual mentioned avoiding direct rain although it should withstand some drops of rain with the cover. The only hassle is the whole syncing thing. if you have two or more 'external' sensors then you have to remove the batteries of the base unit and the 'external' sensors if any unit needs a batterie change. but i'm hoping that batteries won't run out anytime soon. Even with this minor incovenience i would still recommend this unit and La Crosse tech in general to others.
Accurate, cheap and quality February 15, 2009
S. Patten (Melbourne, Australia)
This unit arrived via mail redirection to me in Victoria Australia,
Just in time to measure the hottest day in our history in Melbourne.
Our hot-house recorded 50.2C (118.9 F) on one sensor and the other two sensors that I had gave me other temperatures at a flick of a button to highlight 46.7C in the shade and on the dark side of the house. Needless to say it was a warm one. The unit and sensors were easily mounted and become online once the unit started to talk to them. I had others sensors around and they were spot on for accuracy without any calibration. If only they could produce rain it would be perfect.
