In this article I have explained about a peak detector circuit, its working principle and how to implement it in clap operated circuits for illuminating an LED in response to clap sounds. What is Peak Detector A peak detector is a circuit which holds maximum amplitude value of a signal. If a signal varies rapidly […]

Simple LDR Motion Detector Alarm Circuit
Here I have explained how to build a simple LDR based motion detector sensor circuit using ordinary parts such as LDRs and opamps, reasonably accurately. What are Motion Detectors Motion detector or sensor alarm is a device which detects the presence of a motion or movement within a certain fixed range and raises an alarm […]
Ultrasonic Detector Circuit [Extend your Ear’s Sensitivity]
The ultrasonic detector or receiver circuit will be able to detect all those high frequency sounds that are beyond the hearing capacity of humans. The units will be able to hear all those frequencies that are perhaps only audible to some animals like dogs, cats and bats. The ultrasonic receiver circuit can be used for […]

Introduction The device CS209A is a bipolar monolithic IC specifically designed for metal detecting circuit applications. The IC fundamentally has a built-in oscillator stage, a couple of current regulator stages, a […]
Lamp Outage Detector Circuit for Car Turn Signal
The O.E.M. turn signal flashing units installed in automobiles have two basic functions i.e. Flasher and Lamp outage detection. These flashers are usually built with an 8-pin IC like U2044B, U6432B etc. which are specifically made for automotive flashers. Designed and Written By Abu-Hafss Circuit Operation These flashers normally oscillate at about 1.4Hz. When a […]
