Following the popular WS-2000 weather station, RainWise introduces the MK III. It is a wireless, solar powered weather station with new features - including integrated rain gauge and multi-display. The MK III wireless Weather Station is easy to install and use. The roof top sensor assembly is wireless and solar powered, allowing it to operate for many years without servicing. With a range of up to 400 feet at 315mhz you can place Oracle displays almost anywhere in your home or office.

With the computer interface you can collect, analyze and build a data base of your local weather.

The MK III Measures:

• Wind Speed
• Wind Direction
• Temperature
• Inside Temperature (multi-display only)
• Barometric Pressure
• Rainfall
• Relative Humidity
• Wind Chill
• Dew Point
• Temperature/Heat Index (multi-display only)
• Clock and Calendar (visible with multi-display only)
• Minimums & Maximums

The MK III Sensor Assembly broadcasts the weather data to one or more receivers, such as the Weather Oracle Display, Weather Oracle MK III & Computer Interface (see below). This means that you can have as many displays and computer interfaces in a building as you like, using just one sensor assembly - Great for condominiums, schools, offices, etc. A new feature to the MK III is the option for a wireless yard-mount rain gauge. If the rain collector ever needs cleaning, the yard mount is easily accessible.
The MK III Wireless Sensor Assembly, the Weather Oracle, the Weather Oracle MK III and the Computer Interface are Guaranteed for two (2) years. The solar panel is guaranteed for five (5) years.
