Automatic controller to water plants

Abstract: Despite the massive demand of water for plant irrigation, there are few devices being used in the automation of this process in agriculture. This work evaluates a simple controller to water plants automatically that can be set up with low cost commercial materials, which are large-scale produced. This controller is composed by a ceramic capsule used in common domestic water filters; a plastic tube around 1.5 m long, and a pressostate used in domestic washing machines. The capsule and the pressostate are connec… Show more

“…Our research group developed a low-cost automatic controller for irrigation, sensor-based, which has been proved robust, efficient and can be assembled by farmers themselves (Medici et al, 2010). This controller has the advantage of being built with low cost materials, even though it requires trained personnel for installation and periodic maintenance.…”

“…A automação da irrigação foi realizada por meio do uso de um "acionador simplificado para irrigação" (registro de patente MU 8700270-1 U), cujo funcionamento, processo detalhado de montagem e instalação foi descrito por MEDICI et al (2010), sendo utilizado desnível do dispositivo acionador equivalente à tensão de 5,0 kPa de tensão no solo contido no vaso. Este dispositivo pode ser construído com peças e utensílios domésticos fabricados em larga escala, de baixo custo e de fácil aquisição no mercado, e vem se mostrando eficiente na automação da irrigação, de forma a manter a umidade do solo em níveis próximos à capacidade de campo (MEDICI et al, 2010;BATISTA et al, 2013;CARVALHO et al, 2013;DIAS et al, 2013).…”

“…Irrigation management was performed using the "Simplified Irrigation Device" (SID) (Medici, Rocha, Carvalho, Pimentel, & Azevedo, 2010), which operates in response to soil water tension and is regulated by the unevenness between a porous capsule and a pressure switch.…”
