Temperature/Humidity sensor with OPC UA interface

Our client was searching for an inexpensive and wireless solution to provide temperature & humidity data of their production environment into their OPC based control system. Therefore, we developed a solution based on a Raspberry Pi0 which was connected to a digital DHT11 sensor and provided environmental conditions, such as temperature and humidity via Wifi to the OPC server. As requested by the client, we also implemented the possibility to define fixed IP addresses for this application from the GUI.
