Most homes use appliances such as Refrigerators, Washing Machines, Dishwashers or Clothes dryers or a combination of these. And more appliances means the there is more concern for home owners regarding energy wastage and efficient running of these appliances. This has led appliance manufacturers to design better equipments with lower wattage motors or compressors, with more sensors to monitor the various running states of these appliances so quick action can be taken remain energy efficient. In Dish washers and Washing machines, the processor needs to know that the door is closed and latched, so that the automatic cycle can be started and water can be pumped into the system so that there is no wastage of water and consequently, power. In Refrigerators, the processor needs to not only control the lighting inside the compartments doors are closed to avoid energy wastage, but to also trigger an alarm so the food inside does not get spoiled. All door sensing in white goods and appliances is accomplished with a reed sensor mounted inside the appliance and a magnet on the door.
