How to make a alarm system using Arduino?

For this project, a motion detector alarm system based on an Arduino Uno was created. All of the components along with many more are available in the Elegoo Complete Starter Kit for Arduino R3. The system has the following features:- PIR motion sensor HC-SR501 to detect movement in the proximity of the device.

Can Arduino tell time?

But there is one thing an Arduino cannot do – it can’t tell the time. There are several time-related functions you can use when programming an Arduino: The delay function, which can delay program execution for a specified number of milliseconds.

What is PIR sensor in Arduino?

PIR sensor detects a human being moving around within approximately 10m from the sensor. This is an average value, as the actual detection range is between 5m and 12m. PIR are fundamentally made of a pyro electric sensor, which can detect levels of infrared radiation.

What is PIR sensor Arduino?

How do I connect Arduino to PIR sensor?

PIR connections – Connect the Gnd pin of sensor to the ground of Arduino. Vcc pin of the sensor to 5V of Arduino. And signal / output pin to digital pin 5 of Arduino board. Led connections – Positive terminal of the led to digital pin 9 of Arduino.
