Smart Home Description - Assignment 1
Our Smart Home consists of a door that opens automatically for the person wearing the right RFID-tag. The RFID-tag is placed in the house owners’ shoes or cloths (in our case, the shoes) so that it’s harder to forget or lose. A green light beside the door turns on if a person with the right RFID-tag approaches the door, if someone with another RFID-tag approaches, a red light turns on.
The bathtub in our Smart Home is controlled by a lever and a rotator, making the user able to adjust precisely how much water should be in the tub and what temperature the water should have. When adjustments are set, the user presses a touch sensor and the bathtub fills up automatically. The amount of water and the temperature of the water can be seen on a LCD-screen above the bathtub. The LCD-screen also notifies when the bathtub is filling up with water and when it’s ready.
In the bedroom there is a motion sensor, and in the bed there is a pressure sensor. Together this two sensors can tell if someone is lying still in the bed for a longer amount of time, and thus conclude that the person is sleeping. If the sensors detect this, lights in all rooms, the LCD-screen and the stove will turn of automatically.
The bed has a vibration sensor which can be used to turn off or on the lights (and turn of the stove and LCD-screen). To activate it you just clap hard on the side of the bed. When the sensors register that the user is in the bed for a longer period of time, the mobile client will know that the user is sleeping or at leas lying in the bed. The same goes for the bathtub.
