Oregon Scientific RAR502S

A sophisticated weather station with a sleek colour LCD display allows you to easily monitor the temperature and relative humidity in up to four areas of your house. The master unit itself measures and displays the values directly at the point where you install it, and the three enclosed sensors monitor the data at other areas of your choice. You can monitor not only outdoor temperature and humidity, but also data from different areas in your home. In addition, there are two sensors and the third one features an information display. All communication between the sensors and the main unit is wireless and the measured values from the sensors are displayed in the form of colour-coded digits.
