Interactive detecting power grid load

Well this sounds interesting and seems it is even more actual. Humanity consumes more and more energy every day. When talking about electrical energy – we still depend on electricity that isn’t clean. So why not to start saving. This project won’t lower your electrical bills but will help to save mother Earth a bit. Circuit simply tries to detect when power grid is on a heavy load and delays switching on non crucial devices until high-load period passes. From technical point of view it is enough to monitor AC frequency. If it drops a little below normal 50Hz (or 60Hz) then it indicates that line is loaded and generators feel some brake that tries to stop them. This task is led for Olimex LPC-2478-STK with ARM7 processor. It is… Continue reading
