On-line data acquisition system for Aanderaa weather station

Abstract

Aanderaa Weather Station can be installed at unattended remote places for collection of various weather parameters at regular preselected intervals. The weather parameters are recorded on the magnetic spool inside a battery operated datalogger which is housed in an aluminium box, placed on the ground level. As the recording station is supposed to operate unattended for a long duration of time, a need arose to check quality of data periodically. Hence a datalogger was interfaced to a microcomputer. The scheme adopted to compute the weather parameters instantaneously which can be displayed or printed, or stored on the data cartridge at user's wish is described
