This home smoke detector circuit warns the user against fire accidents. It relies on the smoke that is produced in the event of a fire and passes between a bulb and an LDR, the amount of light falling ...

This is one of the interesting project circuits which is used to detect the flow of air in areas like car engine. It can also be used as temperature detector. This is one of the interesting project ...

A custom comparator IC that has fast response time and hysteresis protects a car's engine control unit from failures on monitored peripherals that create high current conditions. In most modern cars, ...

There are many ways to build a radio receiver, but most have a few things in common, such as oscillators, tuned circuits, detectors, mixers, and amplifiers. Put those together in the right order and ...

Engineers have crafted the world's highest-frequency circuit made with a common type of semiconductor transistor, a step that could slash the price of detectors useful in earlier cancer detection and ...
