All commercially available weather sensors for wind speed, wind direction, rain, rainfall, brightness, light intensity (pyranometer), twilight, air pressure, humidity or temperature can be connected to the device. A power supply unit for supplying the sensors with 24 V DC voltage is integrated. The device can be operated with 115 to 230 V AC, 50/60 Hz. A maximum of 300 mA is available across the entire voltage range. The application software is tailored to the recording of weather data.
