AbstractA custom meteorological monitoring system was constructed to reliably monitor the meteorological parameters of the site of TÜBİTAK National Observatory (TÜBİTAK: The Scientific and Technical Research Council of Turkey). The site is located on a mountain top known as Bakįrlįtepe about 50 km west of the Antalya City at a height of 2547 m. The system has software (C‐based data acquisition/archiving structure and PHP based WEB monitoring support) and micro‐controller based control electronics, fiber based custom designed encoder sensors (for wind speed and direction) and transmission lines using fiberoptic to RS232 transcievers. The constructed system can be used in any robotic telescope project for data monitoring and alert system creation. (© 2004 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
