La Crosse Technology - Wireless Temperature Station with Wireless Temperature Sensor

THese sensors are very inexpensive and very accurate. I bought 4 and placed them side by side and they all agreed within +/- 1 DegF which is great for what I need.

I got this for christmas, It on of my favorite christmas present this year. It is fun to see how cold or hot it is outside

I bought two. One transmitter failed completely within three days the other works only intermittently. Advertised to transmit up to 300', one station is located line of sight within 25' and does not show the outdoor temp for long periods. The other station is located within 40' and does not receive the signal at all. Have reset all devices numerous times.
