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.

A IOT based project that motion or obstacle detection using PIR Sensor, Buzzer, Breadboard, NodeMCU ESP8266, Jumper Wires and etc. • To implement an IoT-based project for motion detection using a PIR ...

The equipment circuit design enables each customer to conne ct this home security system to a distant network using a piezoele ctric buzzer, an LCD board, and a PIR sensor at residences and workplaces ...

It combines an Arduino-compatible processor with a light sensor, a temperature sensor, a 3-axis accelerometer, a joystick, a set of pushbuttons, a slider, an RGB LED, and a buzzer.

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 ...

By reading different values from the sensor, we can detect if is it light , dark or a value between them. Another element that we are going to use on this experiment is Piezo Buzzer. So what is it ?
