The TX7U Temperature and Humidity Sensor reports the outdoor temperature and humidity (or any other location whose temperature and humidity you wish to know) to the station. This remote sensor features its own LCD display for local viewing of the temperature in °F and the relative humidity in percent. The remote has a water-resistant case, but it must not be installed in a location where rain can fall directly on it.

Included with the TX7U is a separate table stand that attaches either to the bottom of the case for placement on a flat surface or to the back of the case to act as a wall-mounting bracket.

This sensor transmits 433 MHz signals and operates on two AA alkaline batteries. Average battery life is approximately one year.
