Motion Detector with Arduino (PIR + LED + Buzzer) This project uses an Arduino board with a PIR motion sensor to detect movement. When motion is detected, an LED lights up and a buzzer sounds. It's ...

This project uses an Arduino Uno to build a burglar detection alarm system with a PIR sensor. The system triggers an alarm when motion is detected, signaling with an LED and a piezo buzzer.

In this blog, we will learn about how to interface a Passive Infrared sensor (PIR Sensor) or motion sensor with an Arduino. We will also learn about how this sensor works and different parts of it. So ...

In this tutorial we are going to interface RCWL-0516 Doppler Radar Sensor with Arduino Nano. The RCWL-0516 is a motion detection sensor. It can detect motion through doppler microwave technology ...

Automating household or office systems can be achieved using an Arduino Nano, a passive infrared (PIR) motion sensor, and a relay. The primary aim is to create a control system that activates or ...

TK has combined a PIR with an Arduino to create a smart safety light for the house or workshop. Follow along as this gets built out into a more extensive project.

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 ...

If you need a PIR motion sensor with a longer range (up to 12 meters), the Everything Presence One Kit, also based on ESP32-S3, is an alternative, but it lacks battery support, comes with much fewer I ...
