Smarts houses are valuable for today rapid changing society. Theycan save energy, water and operational cost, and can improve security, and event response time. This paper describes the implementation of a prototype for a smart house system to control actuators and to control different analog and digital sensors widely used in similar systems. This system is composed of a PIC18F4550microcontroller with different sensors attached to a board and can manipulate electronic circuit peripherals for measuring physical variables in the environment. The PICkit2 application and theUSB.c library were used to program the microcontroller for communication through the USB port. The PC interface program was implemented in Visual Basic using he HID native API for communication through the USB port. SQL server was used to implement a database to collect data from data acquisition module. The implemented prototype smart house system is used to control and monitor temperature, relative humidity, atmospheric pressure sensors, motion detector, smoke detector luminosity intensity detector, and can detect the status of a switch to turn on a light bulb, radio, fun, or any electro domestic device. In conclusion, powerful and versatile information technology was used to implement a prototype smart house providing an efficient and cost effective solution to the current market.
