The 555 timer IC connections are also shown in the schematic ... This circuit can easily determine and trigger the alarm if the fan has been stopped or not working as it should be. 2. In the medical ...

As you can observe that the output waveform is a square wave, so a Zero Crossing Detector is also called a Square wave Generator Circuit. To learn more about op-amps, check other op-amp circuits ...

We are familiar with the missing pulse detector circuit, which detects the occurrence of a missing pulse in a pulse train where the pulses are of equal duration. But this circuit detects the long ...

This is not an infrared motion detector! The IR detector circuit in principle, converts the IR signal pulse trains into noticeable aural ... on a small veroboard or any general-purpose printed circuit ...

This ultrasonic proximity detector comprising independent ... glows because of the signal reflected from the body of the visitor. The circuit can be assembled on any general-purpose PCB. The ...
