The design and implementation of intelligent home control system

In this paper, an intelligent home control system is designed and it can monitor indoor temperature, lights and smog in real time and remote control the home through a pc. This system is composed of an ARM controller which servers as the core controlling chip, a temperature sensor, a smog sensor and a light sensor which function as signal acquisition units, and the peripheral equipments of keyboard, liquid crystal display. What's more, 485 level conversion chip in the system can increase communication distance and realize remote control. With the help of GPRS module, people can control the system via their cellphones and know the real time situation in their house even though they are not there.
