The ESP8266 is a low-cost Wi-Fi chip with full TCP/IP stack and MCU (Micro Controller Unit) capability produced by Shanghai-based Chinese manufacturer, Espressif Systems.
Fuse (electrical)
In electronics and electrical engineering, a fuse is a type of low resistance resistor that acts as a sacrificial device to provide overcurrent protection, of either the load or source circuit.
Switch
In electrical engineering, a switch is an electrical component that can break an electrical circuit, interrupting the current or diverting it from one conductor to another.
Capacitor
A capacitor (originally known as a condenser) is a passive two-terminal electrical component used to temporarily store electrical energy in an electric field.
Electronic component
An electronic component is any basic discrete device or physical entity in an electronic system used to affect electrons or their associated fields.
Liquid-crystal display
A liquid-crystal display (LCD) is a flat-panel display or other electronic visual display that uses the light-modulating properties of liquid crystals.
Resistor
A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element.
Transistor
A transistor is a semiconductor device used to amplify or switch electronic signals and electrical power.
Memristor
A memristor (/ˈmɛmrᵻstər/; a portmanteau of memory resistor) is a hypothetical non-linear passive two-terminal electrical component relating electric charge and magnetic flux linkage.
Potentiometer
A potentiometer, informally a pot, is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider.
Thermistor
A thermistor is a type of resistor whose resistance is dependent on temperature, more so than in standard resistors.
Varistor
A varistor is an electronic component with an electrical resistance that varies with the applied voltage.
Contactor
A contactor is an electrically controlled switch used for switching an electrical power circuit, similar to a relay except with higher current ratings.
Opto-isolator
In electronics, an opto-isolator, also called an optocoupler, photocoupler, or optical isolator, is a component that transfers electrical signals between two isolated circuits by using light.
Cavity magnetron
The cavity magnetron is a high-powered vacuum tube that generates microwaves using the interaction of a stream of electrons with a magnetic field while moving past a series of open metal cavities (cavity resonators).
TRIAC
TRIAC, from triode for alternating current, is a generic trademark for a three terminal electronic component that conducts current in either direction when triggered.
Supercapacitor
A supercapacitor (SC) (sometimes ultracapacitor, formerly electric double-layer capacitor (EDLC)) is a high-capacity electrochemical capacitor with capacitance values much higher than other capacitors (but lower voltage limits) that bridge the gap between electrolytic capacitors and rechargeable batteries.
Crossbar latch
The Crossbar Latch is a technology invented by Hewlett-Packard in October 2001, that HP claims could replace transistors in some applications.
Thermopile
A thermopile is an electronic device that converts thermal energy into electrical energy.
Electromagnetic coil
An electromagnetic coil is an electrical conductor such as a wire in the shape of a coil, spiral or helix.
Memistor
A memistor is a nanoelectric circuitry element used in parallel computing memory technology.
Instabus
Instabus, is a decentralized open system to manage and control electrical devices within a facility.
