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 […]

Smart Street Lamp Circuit with Motion Sensor
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 […]
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 […]
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 […]
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 […]
