Um modelo AWS IoT Events de detector para monitoramento de guindastes

Monitore suas frotas de equipamentos ou dispositivos em busca de falhas ou mudanças na operação e acione ações quando esses eventos ocorrerem. Você define modelos de detectores nos JSON quais especificam estados, regras e ações. Isso permite monitorar entradas como temperatura e pressão, rastrear violações de limites e enviar alertas. Os exemplos mostram modelos de detectores para guindaste e motor, detectando problemas de superaquecimento e notificando a SNS Amazon quando um limite é excedido. Você pode atualizar os modelos para refinar o comportamento sem interromper o monitoramento.
