A Computerized Weather Station for the Apple IIe.

Predicting weather conditions is a topic of interest for students who want to make plans for outside activities. This paper discusses the development of an inexpensive computer-interfaced classroom weather station using an Apple IIe computer that provides the viewer with up to the minute digital readings of inside and outside temperature, barometric pressure, humidity, precipitation, and daily high and low temperatures. Instructions describe methods for creating a working weather disk that contains the main computer program, calibration files, and several programs used to create and read data files for the weather factors being studied. Diagrams illustrate the configurations for the weather station, the wind vane, the shutter station, and the electrical circuitry of the computerized weather system. A supply list for the commercially made components and the BASIC programs of the system are provided. (MDH)
