Many complex circuits and integrated circuits contain zero crossing detectors, but we will deal only with the detector here. The detector produces a pulse each time the mains voltage goes […]
Wire Current Detector Circuit
This simple circuit can be used for detecting 50 Hz current inside a conductor without physically connecting with the conductor. You just have to bring the L1 coil near the […]
Ferrous, Non-Ferrous Metal Detector Circuit
The function of this adsorption type metal detector is to indicate the presence of ferrous and non-ferrous type metals. Its functionality depends on the absorption of magnetic energy. An inductor […]
Radioactivity Detector Circuit
The term “Geiger Counter“ refers to a device which actually counts the number of radio active particles passing through a specified area and while this circuit does not actually count, […]
Static Electricity Detector Meter Circuit
Through this particular little electronic circuit we are able to achieve an effective research laboratory instrument. The circuit indicates using the flashing of the LEDs when there’s an electrostatic fields […]
Flood Detector Warning Alarm Circuit
A flood can occur suddenly due to a cloud burst or due or consistent rains. Floods can cause huge damage and loss to lives and property if it is not […]
