GONZALEZ MANRIQUEZ, Irving Alejandro; LUGO ESPINOSA, Oziel  e  AYALA DE LA VEGA, Joel. Design and development of a Hellmann-type semiautomatic pluviograph. Rev. Mex. Cienc. Agríc [online]. 2016, vol.7, n.1, pp.95-101. ISSN 2007-0934.

The construction of a semiautomatic pluviograph with low-cost materials equivalent to a Hellmann-type with siphon is proposed with the objective of acquiring pluvial precipitation (Pp) data. The development of a software application is presented for the analysis and presentation of the data. In order to automate the pluviograph, an electronic system was built based on a liquid level sensor, a time control module, and a microcontroller for an Arduino system. The system stores the data in a microSD flash memory card. The software is coded in Java and allows for the interpretation of the information captured by the electronic circuit, to consult the data registered by the pluviograph, to display tables with the description of each rain event (storm) and to generate graphs as pluviographs and hyetographs. In the test period of this prototype, a 90% accuracy was confirmed in the total measurements, which allows the use of the device in domestic and professional fields where precipitation readings are required.
