home automation using embedded system

home automation project using embedded system discuss about a profitable  and powerful solution for preserving electrical energy by optimizing electrical appliances such as lights, fans, tube lights  etc., it depends upon  occupants in the house or hall with the help of  embedded system like pic microcontroller. normally all of us always forget to switch off the fan and light in a room, when we leave that room. in this project, if there is no one in the room or house, then the fan and light will be in switched off condition and when any person infiltrates the room, the fan and light will be switched on. a passive infrared (pir) sensor is used to analyze the infra-red light radiating or emitting from any objects or persons in its area of vision.

the passive infrared sensor used in the home automation project will perceive these ir radiations and will give some digital output to the pic microcontroller. temperature sensor lm35 is a precision ic with its output voltage proportional to the measured temperature level of a room in degree celsius. when the pir sensor detects the presence of a person, the controller compares the room temperature measured by the lm35 temperature sensor with a predefined value and according to that, controller will control the fan. the resistance of the ldr will vary in accordance with the incident light intensity. here in the home automation project, these ldr is used to detect the light intensity level of a room and give signals or outputs to the pic microcontroller and according to the readings from the ldr; the microcontroller controls the operations like, switch on the light or any other activities.

to bridge the gap between consumer and expert while allowing for integration into any existing home environment without physical alteration to the building, a modular and flexible smart home automation solution with seamless integration potential is required. in existing smart home automation systems, safety and security is an important consideration for the consumer and end users. a user gains access to the system either locally or remotely over the internet.

as can be seen in fig 1.2, the system has a distributed nature and is organized in a two-level hierarchy. safety and security is an important consideration in the eyes of the end user – not only the network security of the system, but the level of security the system can provide for the home and its occupants. one of the challenges of designing an interface between the user and the system is doing it in such a way that it is made easy for the user to associate the physical devices within their household to the applicable elements within the user interface.
