Engineers have developed a simple Smart Electrical Outlet System (SEOS) that optimizes current consumption and prevents energy waste.
When connected to regular outlets, the devices consume electricity even in standby mode. Although today there are technologies for remote control of various devices, they all require specialized IoT devices. Now a team of researchers from the National University of Singapore has created a simpler system by integrating all the necessary elements into the outlet itself..
SEOS is a network «smart» outlets and NFC (Near Field Communication) stickers that attach to the plug on the power cord of each device. All exits in the building are connected via Wi-Fi to a central server. When one of the plugs is inserted into an outlet, the NFC reader identifies the device by a unique code on the sticker. After the server determines the electrical characteristics of this device in the database, users can turn it on and off over the Internet by simply plugging in or unplugging the outlet..
The system also allows you to check if the device was accidentally left on, tracking its energy consumption in real time.. In addition, you can set a schedule for individual outlets so that they automatically turn their device on and off at specific times of the day.. In addition, if the system detects that the appliance draws more current than indicated, it automatically disconnects the outlet to prevent overheating..
A new type of socket was invented, helping to save up to 60% of electricity
The developers estimate that the cost of installing SEOS for each outlet will cost in the region of $ 80, while reducing the total power consumption of the building from outlets by 30-60%. The system also allows the use of cheaper devices, without elements of the Internet of Things..
Recall that earlier researchers also found a way to improve the heat exchange of heating systems by five times..
