Over the years, control relays of various types have been used by the hundreds — even thousands — to control nearly every function in commercial and industrial processes. Today, many of those ...

GOOSE Messaging (Generic Object-Oriented Substation Events) is the most used aspect of 61850. Replace copper wires with digital one, turn that Lock Out Relay (LOR) into a latch bit in a relay and send ...

The project has been constructed for applications that require automatic temperature control while providing highly accurate thermal control circuit. The LM35 temperature sensor is the heart of the ...

It is very easy to build an “SMS-controlled relay” with the help of a cheap GSM modem module and a small microcontroller board. Here, I’m using the SIM800L and Arduino Nano V3 to develop a nifty ...
