Energy saving device (esd) (t5557/mifare 1 card ) is designed for energy saving and safety of hotels, guesthouses. The switch controls power supply of the room by inserting the rfid card. When guests check-in and insert card into the energy saving device at the side of interior door, the power is available for the electrical equipment in the room (lighting, air conditioner, television, etc.) When guests leave the room, they take out the key card from the energy saving device (guests must pull the card out, because they have to use it to open the door after return), energy saving device shall be off automatically after the delay of 8-12 seconds to ensure energy saving and safety. The consumption of the illumination system in each room in the hotel is approx 2000 watt. If the guests forget to turn off all the electric appliances before they leave the room, which will be a great waste and it's very insecure in the absence of guest. So the energy saving device could help hotel to save the substantive regrettable consumption.
Hotels, with their random occupancy patterns, are finding that smart energymanagement systems maximize their energy savings and peak demand loads to optimize energy consumption in real-time, all year round.
