Abstract: A weather measurement instrument sensor includes a housing having a top surface, a bottom surface, and a sidewall that at least partially define an interior volume within the housing, a first arm coupled to the housing and rotatable relative to the housing between a stowed position and a use position, a second arm spaced apart from the first arm, coupled to the housing, and rotatable relative to the housing between a stowed position and a use position, a first attachment coupled to a distal end of the first arm to facilitate measurement of a first environmental variable, and a second attachment coupled to a distal end of the second arm to facilitate measurement of a second environmental variable. The distal end of the first arm is nearer to the distal end of the second arm in the stowed position than in the use position.

Abstract: A weather sensing system mountable on a tubular member. The weather sensing system includes a weather sensor housing including removably attached first and second housing portions. The first housing portion includes a first open channel and the second housing portion including a second open channel aligned with and opening toward the first open channel. The first and second open channels form an enclosed channel for receiving and fixing the weather sensing system to the tubular member.

Abstract: A multipurpose weather measurement instrument sensor system in which a fan circulates air past temperature and other sensors to ensure their accurate operation, a basin collects rainwater and precisely directs the rainwater into a tipping receptacle to measure the amount of rainwater collected per unit time and a wind speed gauge is provided with a counter-balanced toggle beam to product wobble-free rotation.

Abstract: A method and apparatus for sharing data regarding conditions sensed at one or more user-selected locations with others over the Internet generally or over Internet-accessed social networking systems using sensors located at user-selected locations and servers which are connected respectively to the Internet for communication with client devices or with social networking systems.
