Weather station

Some problems were encountered with false rain alarms. The sensor of the new weather station sometimes triggered when the dust levels were high, while a new sensor that was bought for the old weather station triggered when the humidity was high. When there is a rain alarm, this directly causes to the telescope to close, and this can interrupt and seriously affect observations. It was found that the best way to avoid false alarms was by combining the data from both sensor, were a closing of the telescope is only triggered if both sensors give an alarm.
