The Oracle Display for the MK-III Wireless Weather Station receives the weather instrument data via radio signal from the sensor assembly.

Wind speed and direction are displayed in the compass rose at the left of the display, and all other sensor data is shown in the upper right. In addition to the real-time data, the Weather Oracle records minimum and maximum values, with time of occurrence, for wind speed, temperature, relative humidity, dew point, and barometer. Two independent counters record rainfall. Each rainfall counter shows the time and date of the last counter reset.

• RainWise Weather Oracle-LR Display
