Excellent with certain La Crosse 915 MHz weather instruments

This La Crosse Technology TX27U-IT 915 MHz Wireless Temperature Sensor with LCD is the same Model TX27U-IT that comes standard with and works at the outdoor transmitter for the La Crosse Technology WS-9121U-IT-CBP Wireless Thermometer, which accepts a total of three sensor/transmitters - two in addition to the standard one that come with the wireless thermometer. If you have this particular La Crosse Wireless Thermometer, adding these is an excellent way to monitor the temperature in a child’s bedroom, a greenhouse, a back year, a basement or any number of other locations.

The specs note that the TX27U-IT sensor has a range of 330 feet (100 m). I’ve tested mine at about 250 feet away, and have it mounted outside behind foliage and part of the building about 175 feet away - it works just fine. The 330 feet should be considered as in “open air” with no obstructions and that radio waves like this don’t curve around objects. The actual transmission range depends on how many obstructions (walls, floors, the roof, ceilings, outdoor foliage, etc.) are in the way, and could cut the signal range in half.

Please also note that this is NOT a dual channel model with humidity, rainfall, snow measurement, local bug count, political affiliations of those who pass by or any other function combined. It senses temperature… and that’s it, and it should only be used with other La Crosse 915 MHz weather instruments. If in doubt, check the La Crosse site on the ‘Net for more info, or call their customer support people.

The La Crosse Technology TX29U-IT 915 MHz Wireless Temperature Sensor is anther model that that is similar in function, but it lacks the LCD panel. The La Crosse Technology TX37U-IT 915 Mhz Wireless Temperature Sensor is also similar, and also lacks the LCD temperature display, but is a weather resistant solution where direct exposure could be a factor.

In any case, these are excellent solutions if you want to expand the capability of the wireless thermometer mentioned above… and remember, no more than a total of three remote sensor/transmitters can be used with this unit!

Update (9/6/2010): This item is currently on sale here for the lowest price I’ve seen.

Good indoor unit
I purchased this for my son bedroom. I get the temp displayed downstairs on the main unit and also able to see the temp on the unit itself if I am upstairs in his room. He can also see the temp himself.

Good but maintenance cost too high
I bought this and it worked well. I got fed up with the cost of maintenance and continued use. The cell button in the outdoor unit does not even last a month. An average of $ 3.50 a piece, it costs about $ 40 per year for the unit to the outside only. You add the cost of AA batteries for the unit indoors, it will be easily $ 50 per year, which I think is too high.
