In an era where homeowners frequently leave for work or education, robust security for residences is imperative. Traditional security measures, including window and door locks, present challenges such ...

Motion sensor alarms are readily available in the market, but these are expensive. Here is a simple and inexpensive Arduino based motion sensor alarm with voice alert. It can be used for security ...

Functionality: Arduino code written entirely in C++ without utilizing sleep mode functionality. Controls an LED based on motion detection from a PIR sensor. Turns on the LED for a specific duration ...

Code for arduino that makes fade in/out effect after receiving signal from switch, PIR sensor, etc. Default pinout: Pin 9 - main output. That's where you connect your LEDs. Of course you can change ...

Step 3: Working Of The Circuit The working of this circuit is very simple. At first, the state of the PIR sensor is set to LOW. it means that no motion is detected. When a motion will be detected by ...

It can detect motion through doppler microwave technology through walls or other materials. It will get triggered not only by people but also by other moving objects. Later on, in this tutorial, we ...

The real-time PIR sensor in Proteus senses the motion of a particular area. As Proteus is the EDA, to show the motion, a TestPin is present on the sensor. I used the toggle pin here to indicate the ...
