2 Simple Motion Detector Circuits using PIR

PIR with delay ON alarm

The post discuses two simple motion detector circuits using op amp and transistor. We also discuss the pinout details of the standard passive infrared (PIR) sensor RE200B. The first circuit uses an op amp, while the second design works with a single transistor and relay for detecting the IR radiation from a moving human body … Read more2 Simple Motion Detector Circuits using PIR

5 KVA to 10 KVA Automatic Voltage Stabilizer – 220 Volts, 120 Volts

In this article we discuss an easy to build a 7 stage high wattage in the order of 5000 to 1000 watts stabilizer circuit which can be used  for controlling our mains AC line fluctuations and for producing very accurate stabilized voltage outputs for our domestic electrical appliances. Circuit Operation The proposed Accurate 7 relay OpAmp Controlled Mains … Read more5 KVA to 10 KVA Automatic Voltage Stabilizer – 220 Volts, 120 Volts

Remote Control Tester Circuit

Remote control tester circuit using an opamp

We all use remote control handsets for controlling various household devices such as TV, AC, Music systems, curtains etc, and sometimes we seem to have problems with these devices, or even a newly purchased remote controller unit occasionally seem to malfunction, and identifying the issue becomes quite difficult for us. This simple 2 transistor circuit … Read moreRemote Control Tester Circuit
