KY-025 Module : PinOut, Features, Specifications, Interfacing, Working, Datasheet & Its Applications
The reed switch is a type of electromechanical switch that operates through the principle of magnetism. Professor Valentin Kovalenkov invented it in 1922 at the Petrograd Electrotechnical University (PEU). Walter B. Ellwood developed it into the reed relay in 1936 at Bell Telephone Laboratories. Generally, these switches include a set of ferromagnetic flexible metal contacts, which seal hermetically in a glass envelope. Typically, a magnetic field keeps these contacts open; otherwise, they close … [Read more...]

MCP1640 IC : PinOut, Features, Specifications, Circuit, Working, Datasheet & Its Applications
A synchronous step-up DC to DC-converter is an integrated circuit that enhances voltage supply from an input to an output. So this type of SMPS (switched-mode power supply) utilizes a minimum of two semiconductors like a transistor, a diode, and a single energy storage element. These converters are more efficient than nonsynchronous converters including 95% optimal operation efficiencies. The applications of this converter involve powering natural LED panels, charging white LED backlights, … [Read more...]
LED Traffic Light Module : PinOut, Features, Specifications, Interfacing & Its Applications
The first traffic light (stoplights or traffic signals) was launched in December 1868 in London on Parliament Square to decrease the requirement of traffic police officers to control traffic. These systems use electricity & computerized control with superior traffic light technology and improved intersection capacity. This system can also be used for purposes like pedestrian movement control, railway level crossings, and variable lane control like smart motorways and tidal flow systems. … [Read more...]
KY-024 Hall Sensor : PinOut, Features, Specifications, Interfacing, Working & Its Applications
A linear magnetic hall sensor or hall-effect sensor is a module named after the physicist Edwin Herbert Hall who discovered the Hall-effect phenomenon. So this sensor detects the magnetic field strength by producing a voltage across a conductor whenever a current is supplied throughout it while arranged in a magnetic field. So it converts the magnetic field strength essentially into an electrical signal. Thus, the examples of linear magnetic hall sensors are KY-024, 49E, A3144, KY-035, etc. This … [Read more...]
LM337 IC : PinOut, Features, Specifications, Circuit, Working, Datasheet & Its Applications
