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. In this manner, the data output that is provided to the remote receiving station appears to be real time continuous transmission but is actually delayed by the length of time of the data transmission interval. While the invent…
