CF Bom dia,

Em primeiro lugar você tem que ler este post para saber como deve publicar o seu código.

http://labdegaragem.com/forum/topics/sugest-o-de-como-postar Use o pastebin ou anexe um txt.

Depois trate de dar ainda que seja breve, uma descrição do seu problema, nota-se que esta usando um sensor de humidade e temperatura DHT11, mas não explica como e para que esta fazendo isso, então fale o que esta projetando, que pinos esta usando, se tiver foto ou circuito anexe, ou link de site do projeto coloque aqui, e descreva qual é o seu problema, você poderia estar usando a biblioteca errada ou poderia ser um erro humano, então se não descrever corretamente seu problema e publicar de modo correto o seu código, mesmo querendo, nem eu, nem os colegas aqui não vão poder te ajudar.

Abs.

Sr. CF, bom dia.

A solução do seu problema é muito fácil.

faça assim :       sfovck  b.hh'g[  fb,hb,gljh 8fbfun;b[m,  vobovbniooboç;;;  

e depois;

skvrt . kdkdk4 v'fnwb wlcjf xcljkxlc;   rfgfgf

 e ele estará resolvido.
