This simple yet highly sophisticated, smart LED street light circuit automatically switches ON a street lamp from low brightness to high brightness whenever it detects a moving object underneath it. This action is initiated only during nighttime, while during daytime the street lamp remains completely shut off. What this Circuit will do This advanced automatic […]

How to Connect and Use RCWL-0516 Microwave Motion Sensor
In this article I will comprehensively explain about the RCWL-0516 a microwave proximity motion sensor which uses Doppler radar. Here, I will elucidate the following points: What is RCWL-0516 It is yet another type of proximity motion sensor which can detect if someone has entered into an area, and raise an alarm or take an […]
Ultrasonic Motion Detector Circuit
This ultrasonic motion detector circuit project picks up movement of any object including human beings from a distance of 4 to 7 meters away. As soon as the motion is detected, the output of the circuit illuminates a red LED indicating the presence of an obstacle or an intruder. However, using supplemental circuit stages connected […]
Motion Detector Circuit using Doppler Effect
The motion sensor circuit explained in the article works by using doppler shift principle, in which the moving target is detected through the continuously varying frequency, reflected from the moving object. What is Doppler Effect One very fascinating feature of sound is the Doppler effect. The Doppler effect happens when the source that is producing […]
5 Simple Motion Detector Circuits using PIR
A PIR motion sensor alarm is a device which detects the infrared radiation from a moving human body and triggers an an audible alarm. In this post I have explained 5 simple motion detector circuits using op amp and transistor. We also discuss the pinout details of the standard passive infrared (PIR) sensor RE200B. We […]
Fishing YoYo Stop-Motion Switch Circuit with Indicator
In this post I have explained a stop-motion switch circuit or a strike indicator for aiding fishing yo yo applications. The idea was requested by Mr. Mike. Technical Specifications (kindly bear the long discussion) Hello Sir, My name is Mike. I am the one requesting help with this stop-motion switch from the “Homemade Circuits” Blog […]
