Abstract: A wireless weather station for measuring a number of weather parameters over an extended time at a data collection location. The weather data can be transmitted to a remote location using substantially less total power than would be necessary to provide real time continuous transmission, yet provide the appearance of real time continuous transmission. A sensor assembly is positioned at the data collection location, powered by a battery that is recharged using a solar panel. A clock controlled microprocessing unit controls the data transducers to provide a data sampling rate and a data transmission interval. The data sampling rate for a parameter corresponds to the rate of change of the parameter. The microprocessor unit provides a plurality of data transmission intervals, with each of the data transmission intervals having a predetermined length of time corresponding to the power requirements of the sensor assembly and the current power status of the battery.
