Circuit of test : The following assembly is a meter of relative humidity (without compensation of temperature) which utilizes a sensor integrated SHT11, a pic16F876 and a LCD microcontrolado.
The measure is shown by screen representing a percentage of relative humidity and is brought up to date each 2 seconds.

The plan for the assembly is the following: 
It notes: itself Not the printed circuit due to the simplicity of the assembly has been carried out, that can be done in protoboard without problems.
