La Crosse Technology TX28U-IT 915 MHz Wireless Thermo-Hygro Sensor Review

Average Reviews:

(More customer reviews)Very dependable and accurate readings, batteries last a good length of time. My only issue is with the "connection" to the base unit. The base unit requires batteries (no option for plugging it in) and when the base unit batteries need replacing then all remote sensors need resetting as well - very time consuming.

Monitor outdoor weather conditions in every corner of the yard by adding an extra wireless temperature and humidity sensor to a household La Crosse Technology weather system. The TX28U-IT wireless thermo-hygro sensor transmits temperature and humidity readings to a base unit to enable users to plan appropriately for brisk, hot, or damp weather.

Outdoor temperature measurement capabilities range from -39.9 to +139.8 degrees F, while humidity levels assessed range from 1 to 99 percent. The sensor\'s small LCD screen alternates between displaying the current temperature and current humidity data. To ensure the most accurate readings, install the sensor out of direct rain and sunlight; the sensor can conveniently be mounted upright or on a wall.

Oregon Scientific THGR122NX Wireless Temperature and Humidity Sensor Review

Average Reviews:

(More customer reviews)Product works as expected. From my experience Oregon Scientific Weather Stations are one of the best. The batteries last over a year and they are very accurate. After comparing different brands that people I know had I settled on a Oregon Scientific BAR388HGA and am very satisfied with it. I bought this sensor mainly to monitor the temperature in a second floor room. The sensor is approximately 60 feet away, up one floor and through several wall from the main unit, and it work very well.

Compatible with over 50 Oregon Scientific products, this thermo-hygro sensor transmits temperature and humidity readings back to a main display unit, available separately. Most main units come with a single sensor; incorporating an additional sensor like this model makes it possible to monitor conditions in another point of interest. Readings can be taken indoors or out, so it is easy to tell at a glance the conditions in the backyard, the greenhouse, the wine cellar, the garage, or the crawlspace. Transmissions repeat every 40 seconds, so information is always current and accurate.
Centered around an easy-to-read LCD digital screen, the sensor displays the current humidity level as well as the temperature. It also indicates which of the three channels the transmission is currently set to. The unit\'s instruments are accurate within the range of -22 to 140 degrees F, and they travel up to 100 feet, barring obstruction, so finding a mounting location is easy.
To ensure accurate readings, the sensor should be mounted with the included hardware in a dry location and out of direct sunlight. Two AAA batteries, not included, are required for operation, and lithium batteries are recommended for use in sub-freezing weather conditions. Compactly built, the sensor measures a trim 2-2/5 by 3/4 by 3-2/5 inches, and Oregon Scientific backs it with a limited one-year warranty.
