This paper presents a mobile phone based Intelligent home system equipped with motion sensor, smoke detector, temperature sensor, humidity sensor and light sensors. The sensors are controlled by a microprocessor PIC 18F4520 through the Short Message System (SMS) having password from the user or any mobile used for secure operation of the Intelligent home. The microprocessor after completing the required task contained in the SMS reads the sensor measurements of respective sensor and then feedback to the user by SMS in an average time of 20.3 s. Intelligent home has been designed such that if there is any emergency, it will send an emergency SMS to the user in about 9.26 s. The operation of the Intelligent home has been successfully tested on Vodafone-Fiji network and can work with other networks in the world.
