Automatic humidity control system

This project is designed to detect the humidity percentage and temperature in the environment. Hence, it will control the humidity to the normal percentage of humidity by output produced from this project which is DC fan and LCD that will turn on and display percentage of humidity. This is also one of the ways to overcome the problem of electronic devices always malfunction. Furthermore, this project consists of buzzer and LED which helps to alert people nearby if that time the humidity percentage is high. The coding for the programmable IC (PIC16F877A) microcontroller has been generated using MikroC while Proteus 7 is used to design and simulate the circuit by drawing the schematic diagram in ISIS and PCB layout in ARES. It is important to do the simulation first before fabricating the design prototype to prevent any mistake that will affect our expected output. After that, the circuit is tested on the breadboard to get the expected result. It is observed that electronic devices can be prevented from malfunction. At the same time, can save cost because mostly electronic devices not broken even the humidity low or high.
