Smart Street Lamp Circuit with Motion Sensor

Last Updated on November 9, 2024 by Swagatam Leave a Comment

mart street light circuit

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 […]

Motion Detector Circuit using Doppler Effect

Last Updated on October 21, 2020 by Swagatam 4 Comments

doppler proximity compressed

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 […]
