A weather station is a facility, either on land or sea, with instruments and equipment for measuring atmospheric conditions to provide information for weather forecasts and to study the weather and climate . The measurements taken include temperature , atmospheric pressure , humidity , wind speed , wind direction , and precipitation amounts. Wind measurements are taken with as few other obstructions as possible, while temperature and humidity measurements are kept free from direct solar radiation, or insolation . Manual observations are taken at least once daily, while automated measurements are taken at least once an hour. Weather conditions out at sea are taken by ships and buoys, which measure slightly different meteorological quantities such as sea surface temperature (SST), wave height, and wave period. Drifting weather buoys outnumber their moored versions by a significant amount.
58-516: The term réseau derives from a French word meaning "network". It may mean: a network of fine lines on a glass plate, used in photographic telescopes to make a corresponding network on photographs of the stars: see Réseau plate a system of weather stations under a single agency, or cooperating on common goals an intelligence network as used by John Le Carré, in Tinker, Tailor, Soldier, Spy , chapter 11.
116-674: A copyright license may control the distribution of the source code or design documents, a patent license may control the use and manufacturing of the physical device built from the design documents. This distinction is explicitly mentioned in the preamble of the TAPR Open Hardware License : "... those who benefit from an OHL design may not bring lawsuits claiming that design infringes their patents or other intellectual property." Noteworthy licenses include: The Open Source Hardware Association recommends seven licenses which follow their open-source hardware definition . From

Moored weather buoys range from 1.5–12 metres (5–40 ft) in diameter, while drifting buoys are smaller, with diameters of 30–40 centimetres (12–16 in). Drifting buoys are the dominant form of weather buoy in sheer number, with 1250 located worldwide. Wind data from buoys has smaller error than that from ships. There are differences in
464-585: A particularly active area for open source ideas to move between them. Examples of open-source hardware products can also be found to a lesser extent in construction (Wikihouse), textile (Kit Zéro Kilomètres), and firearms ( 3D printed firearm , Defense Distributed ). Rather than creating a new license, some open-source hardware projects use existing, free and open-source software licenses. These licenses may not accord well with patent law . Later, several new licenses were proposed, designed to address issues specific to hardware design. In these licenses, many of

580-586: A proprietary license, and the Balloon Project wrote their own license. The adjective "open-source" not only refers to a specific set of freedoms applying to a product, but also generally presupposes that the product is the object or the result of a "process that relies on the contributions of geographically dispersed developers via the Internet ." In practice however, in both fields of open-source hardware and open-source software, products may either be
638-955: A scientific journal HardwareX . It has featured many examples of applications of open-source hardware for scientific purposes. Further, Vasilis Kostakis [ et ] et al have argued that open-source hardware may promote values of equity, diversity and sustainability. Open-source hardware initiative transcend traditional dichotomies of global-local, urban-rural, and developed-developing contexts. They may leverage cultural differences, environmental conditions, and local needs/resources, while embracing hyper-connectivity, to foster sustainability and collaboration rather than conflict. However, open-source hardware does face some challenges and contradictions. It must navigate tensions between inclusiveness, standardization, and functionality. Additionally, while open-source hardware may reduce pressure on natural resources and local populations, it still relies on energy- and material-intensive infrastructures, such as

In a 2015 article in Wired Magazine, he modified this attitude; he acknowledged the importance of free hardware, but still saw no ethical parallel with free software. Also, Stallman prefers the term free hardware design over open source hardware , a request which is consistent with his earlier rejection of the term open source software (see also Alternative terms for free software ). Other authors, such as Professor Joshua Pearce have argued there
1160-929: Is required for record keeping. Automatic transmission of data, in a format such as METAR , is also desirable as many weather station's data is required for weather forecasting. A personal weather station is a set of weather measuring instruments operated by a private individual, club, association, or business (where obtaining and distributing weather data is not a part of the entity's business operation). Personal weather stations have become more advanced and can include many different sensors to measure weather conditions. These sensors can vary between models but most measure wind speed, wind direction, outdoor and indoor temperatures, outdoor and indoor humidity, barometric pressure, rainfall, and UV or solar radiation. Other available sensors can measure soil moisture, soil temperature, and leaf wetness. The quality, number of instruments, and placement of personal weather stations can vary widely, making

Examples include: Open hardware companies are experimenting with business models . For example, littleBits implements open-source business models by making available
1334-614: The Four Freedoms . The term hardware in open-source hardware has been historically used in opposition to the term software of open-source software. That is, to refer to the electronic hardware on which the software runs (see previous section). However, as more and more non-electronic hardware products are made open source (for example WikiHouse , OpenBeam or Hovalin), this term tends to be used back in its broader sense of "physical product". The field of open-source hardware has been shown to go beyond electronic hardware and to cover

1856-802: The Internet. Despite these complexities, Kostakis et al argue, the open-source hardware framework can serve as a catalyst for connecting and unifying diverse local initiatives under radical narratives, thus inspiring genuine change. OSH has grown as an academic field through the two journals Journal of Open Hardware (JOH) and HardwareX . These journals compete to publish the best OSH designs, and each define their own requirements for what constitutes acceptable quality of design documents, including specific requirements for build instructions, bill of materials, CAD files, and licences. These requirements are often used by other OSH projects to define how to do an OSH release. These journals also publish papers contributing to
