Abstract
A wireless wind-powered anemometer comprising: a wind reacting device; a rotatable shaft in communication with the wind reacting device; an ac generator in communication with the rotatable shaft, and where the ac generator is configured to produce an ac voltage that is generally directly proportional to wind speed detected by the wind reacting devices; a signal conditioning and transmitter circuit in communication with the ac generator; and where the signal conditioning and transmitter circuit is configurable to communicate with a wireless network, and where the signal conditioning and transmitter circuit is supplied with power from the ac generator. A wireless wind-powered anemometer comprising: a plurality of conic cups; a rotatable cap fixedly attached to the plurality of conic cups; a shaft fixedly attached to the rotatable cap; a shaft housing rotatably attached to the shaft, and configured such that the shaft rotates with respect to the shaft housing and the shaft housing remains stationary; a first bearing in communication with the shaft and the shaft housing; an electronic housing fixedly attached to the shaft housing; an armature located within the electronic housing and f…
