Perfect for a garden, greenhouse, wine cellar, or baby's room, this remote, wireless sensor--designed as an add-on for use with any Oregon Scientific cable-free thermo-hygrometer monitor--displays the indoor or outdoor temperature and humidity where it's located and also radios the data to the monitor, which is not included. The sensor can be placed up to 90 feet away from the monitor, and the channel it uses can be selected from among three options, permitting this sensor to be used with two others by the same monitor. It displays temperature in either Celsius or Fahrenheit, with a range of minus-4 to 140 degrees F. It operates on two AA batteries (which are not included), has a low-battery indicator, measures 4-1/8 by 2-3/4 inches, and can be set on a flat surface with a stand or mounted on a wall (stand and wall mount are included).
