Basic motion sensing setup using Arduino, PIR sensor, LEDs, and push button for interaction & Motion-triggered alarm system with Arduino, PIR sensor, piezo buzzer, and LED alert. // first pic This ...

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. This code ...

Motion detection is a common application for intruder alarms, light switches, and other home and industrial automation applications. And there are several ways to do it. We have already used a PIR ...

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 ...

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 ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion and excites a light source in a flash. The “snooper” here is an ordinary passive infrared (PIR) motion ...

An infrared proximity sensor, or IR Sensor, is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This interfacing of the IR sensor module with Arduino is ...

Recently, I exhausted my stock of common passive infrared (PIR) motion sensor modules and was looking for a new one to play with. I searched the web for a small type with self-contained electronics.

Smart Bee Designs’ Bee Motion is an ESP32-S2 board with a PIR motion sensor, some GPIOs for expansion, and promising over a year of battery life under the right circumstances. If the name “Bee Motion” ...
