VELASCO MARTINEZ, Víctor Daniel et al. Development and validation of a low price automatic weather station for agriculture. Rev. Mex. Cienc. Agríc [online]. 2015, vol.6, n.6, pp.1253-1264. ISSN 2007-0934.

The quantified meteorological observations are important in agriculture to increase productivity. One of the instruments used are automatic weather stations. Stations used in Mexico, generally acquired technologies in developed countries, so that, when the equipment brakes, cannot be repaired because of the cost and lack of knowledge. For agricultural research, most commercial stations are not always the most appropriate, since they are no adjustable parameters required for the research. This paper presents the development of a prototype of an automatic weather station by students from the Technological Institute of the Laguna, which can be adjusted to different sensors and sampling times. Also, the installation of the prototype is detailed in the experimental field of Antonio Narro Agrarian Autonomous University, Unit the Laguna, followed by the statistical validation obtained by correlating readings to historical prototype of two commercial stations installed in a smaller radius than 10 km. Global radiation for a correlation of 0.95 and 0.91 temperature was obtained. Finally scope and limitations of the prototype in agriculture are also analysed.
