In the period 2013-2014 the project “Upgrade and Extension of the Climate Station at DTU Byg” is carried out at DTU Byg. The aim of the project is to renew the hardware and the software for data acquisition and monitoring, exchange cables and cable connections in order to avoid interference of electrical noise from the surroundings and exchange worn out equipment. Further, the aim is to make measured data from the climate station easily available for the users.
