Sim800l | GSM Home Security using Arduino | PIR Motion Sensor Alarm

In this video tutorial, I will show you how to make GSM Home Security using Arduino UNO , SIM800L GSM Module and PIR Motion Sensor. This gsm based burglar alarm system detects motion by using pir motion sensor and sends data to arduino and then arduino microcontroller sends call alert to the emergency number through the sim800l GSM module.

This is a very simple and easy to build home security system with just few lines of code. you can build this security system at home with a little efforts.

[dolar]

it doesn't work, the phone rings by itself without detecting motion

[PersianEngineering]

it doesn't work for me 🙁

Help please

[aedrianefabian]

If I'll be using the barrel plug in Arduino Uno, do I still need to change something in the code? Thank you for your answer

[vainavihome]

Can the same program be used for Arduino Nano

[yipyap]

If i change sa pir senor to sound sensor do i need to change the code?
Hoping for imidiate response 🙏

[biswa]

i am using ir sensor instead of pir sensor and using the same code as given below. but after completing all the steps, call as going automatically without even sensing something, even after I disconnect my my ir sensor output to arduino, still it calls automatically, please help me out, I am stuck

Bro can i use vibration sensor rather than motion sensor? Need help for my project please!!

Dear Ahmed, I tried to adapt the millis code you gave to my own code, but it doesn't work, I couldn't. So I could not remove the delay command and replace it with the millis command. Although I failed, I will write the code I worked on below. I'm asking you, what could be the problem in this code? I would be glad if you help.

''''
#include <SoftwareSerial.h>
long previousMillis = 0;
long interval = 20000;
SoftwareSerial mySerial(3, 2);
int pirsensor = 11;
void setup() {
randomSeed(analogRead(0));
Serial.begin(9600);
mySerial.begin(9600); // original 19200. while enter 9600 for sim900A
Serial.println(" logging time completed!");
pinMode(pirsensor, INPUT);
delay(100);
}
void loop() {
unsigned long currentMillis = millis();

if(currentMillis - previousMillis > interval) {

previousMillis = currentMillis;
}

if ( digitalRead(pirsensor) == HIGH)
{
Serial.println("making call");
mySerial.println("AT"); //Once the handshake test is successful, i t will back to OK
updateSerial();
mySerial.println("ATD+ // change ZZ with country code and with phone number to dial
updateSerial();

mySerial.println("ATH"); // hang up
updateSerial();
delay(2000);
mySerial.println("AT"); // SEEKING 2nd TEL
updateSerial();
mySerial.println("ATD+ // change ZZ with country code and with phone number to dial
updateSerial();

mySerial.println("ATH"); // hang up
updateSerial();
delay(2000);
}
if ( digitalRead(pirsensor) == LOW)
{
;
delay(1000);
}
}
void updateSerial()
{
delay(500);
while (Serial.available())
{
what Serial received to Software Serial Port
}
while(mySerial.available())
{
what Software Serial received to Serial Port
}

}

Kya ham 3.3 volt zenre diaode use kar sakte hai gsm module ko power supply Karne ke liye aurdino se

[-santhoshca]

By using the sim 800l RX pin cannot handle the Arduino TX pin you can't stepdown the power why?

[KanuChinasa]

I love this work. Please I'm confused on how to get the code for programming the Arduino. Thanks your answer

I'm doing this project at school could you help me on discord on some mistakes

Bro, can I use sim 900a for this project?

[MuhaimenSalik-oo]

hey sir ahmad i used tilt ball switch instead of PIR sensor and it works but there’s seems a delay like it is not consistent, sometimes it works and sometimes it’s not please i need help for my project
