The weather station consists of a Vaisala WXT536 multisensor, which can measure wind speed, wind direction, barometric pressure, air temperature, relative humidity and rainfall. Global radiation will be measured by a Kipp & Zonen CMP3 pyranometer, solar radiation by a Kipp & Zonen SP Lite 2 pyranometer. For the PAR measurement a Kipp & Zonen PQS1 PAR Quantum Sensor will be used.

To read the Data from the WXT536 Module we connected an rs485 to USB converter. This protocol will be used when the weather station is permanently installed in Kleve. The WXT536 accepts a voltage range from 6-24V, so we had to connect an external power supply.
