  4. Olá estou procurando um esquema de circuito eletrônico para nível de caixa d’água, que tenha as seguintes medidas, 25%, 50%, 75%, 100%, através de sensores por fios e que tenha visor LCD para indicação. Também quero outo esquema que mim indique 50%, 75%, 100%, através de sensores com fios e tenha visor LCD, não sei se uma placa só serve para os dois casos. se você tiver algum me envie por favor.

    Atenciosamente,
    José Elaesso da Silva.
