Este livro trata simplesmente da conceção e construção de um secador de mãos automático com indicação de temperatura variável. Este projeto centra-se na conceção e construção de um sistema de secagem de mãos automático, com indicação de temperatura. Durante a conceção, foi utilizado o software profissional Proteus 8 para simular o trabalho de projeto. Na causa da implementação deste projeto, foi utilizada uma metodologia Top-down. O microcontrolador AT89S52 foi utilizado para coordenar outros componentes, como o sensor de temperatura e o ecrã de sete segmentos. O sistema de secagem de mãos utiliza um sensor de temperatura linear LM35 para obter leituras de temperatura do elemento de aquecimento que produz ar quente. Além disso, foi utilizado na construção um visor de sete segmentos para apresentar as leituras do IC de temperatura, um ventilador de CA para empurrar o ar quente através de um respiradouro, um relé eletromagnético SRD-12VDC-SL-C para ligar/desligar o secador de mãos, um sensor passivo inferido DSN-FIR800 para detetar objectos como a mão humana e a unidade de alimentação para a distribuição de energia de todo o sistema do projeto. Após a montagem e o teste do sistema, verificou-se que este estava a funcionar perfeitamente bem.
