Abstract

SISTEMA E MÉTODO PARA MONITORAR A SAÚDE DE SENSORES DE BAIXO CUSTO USADOS EM MEDIÇÃO DE UMIDADE DO SOLO. Essa divulgação se refere geralmente a um sistema e um método para monitorar o desempenho de sensores de baixo custo dobrados em um campo para medição de umidade do solo. Os sensores de baixo custo são calibrados para fornecer parâmetros derivados úteis para apoiar a agricultura, tal como o conteúdo volumétrico de água (VWC) do solo. Além disso, as etapas estão sendo incorporadas para eliminar o ruído de sua resposta para derivar medições estáveis similares a sensores robustos caros. A calibração do sensor de baixo custo e a normalização dos valores de entrada do sensor de baixo custo baseiam-se em valores determinados por meio de sensores robustos para medição de umidade do solo. A normalização envolve encontrar um valor mínimo e um valor máximo de umidade do solo. O desempenho dos sensores de baixo custo é analisado com base em uma faixa de valores de umidade do solo. Finalmente, a análise de desempenho fornece estágios de degradação e com base nos estágios de degradação as recomendações avaliadas para modificar o sensor são compartilhadas com o usuário.
