Wireless light switches eliminate the wire from the light to the switch location. This is useful in remodelling situations where new wiring can be a hassle. Rather than tearing down a wall to gain access to the wires, a wireless switch can be used. This avoids any need to access wires and makes remodelling fast and simple.
Li-Fi (also written as LiFi) is a wireless communication technology which utilizes light to transmit data and position between devices. The term was first introduced by Harald Haas during a 2011 TEDGlobal talk in Edinburgh.
Wi-Fi microcontrollers enable Wi-Fi connectivity for devices so that they can send & receive data and accept commands. As such, Wi-Fi microcontrollers can be used for bringing otherwise ordinary devices into the realm of the Internet of things .
The Lightning Switch transmitter requires no outside source of electricity.Each time the transmitter button is pressed, the transmitter converts the mechanical energy supplied by the user's finger into electricity to power a radio transmission to a receiver/relay through the use of a piezoelectric generator (brand name: Lightning) originally invented by the National Aeronautics and Space ...

Wire crossover symbols for circuit diagrams. The CAD symbol for insulated crossing wires is the same as the older, non-CAD symbol for non-insulated crossing wires. To avoid confusion, the wire "jump" (semi-circle) symbol for insulated wires in non-CAD schematics is recommended (as opposed to using the CAD-style symbol for no connection), so as to avoid confusion with the original, older style ...
